Hello all -- this is Jay Berkenbilt, one of the longest time members of
this group, and the second ever solver of mc4d back in October, 1998. I've
been mostly lurking on this list since its formation, popping up every now
and then. Several weeks ago, I ordered my physical 2x2x2x2 puzzle and then
sequestered myself to do my own analysis and solution, free of spoilers
from the list. I have completed this, and I'm now ready to share my work,
dive in, and join all the discussions. I'm looking forward to contributing
and learning.
I have created a YouTube channel
with
my solution videos. You should view these "oldest first". The videos are
numbered in order and also linked below in order. Clicking "Play All" will
show you my videos in reverse order. I don't know how to fix that.
My solution method is as follows:
- Do a full scramble
- Get all the blue and green stickers off the corners -- some will be on
and some off right after full scramble, and the next stage works better if
they are all off the corners
- Get all the blue and green stickers onto the corners starting from all
of them off the corners
- Solve the blue slice
- Solve the green face as much as possible; sometimes there will be a
single corner out of orientation or a pair out of orientation such that one
can't be rotated using regular 3D Rubik's cube moves
- Resolve the final corner orientations
It typically takes me about 15 minutes to do a full solve. I tend to do
things in a fixed order rather than doing much exploitation of things that
coincidentally happen to be in an ordered state.
I have created a series of 11 videos, each ranging in length from about
2:30 to just under 10 minutes, but most are in the 4 to 8 minute range. The
videos are as follows:
- 00: 0:39 personal introduction
skip this unless you're curious about who I am and what I look like. :-)
- 01: 5:18 mapping to mc4d
discussion of how I map this puzzle to the software mc4d puzzle and how I
label the slices.
- 02: 9:19 gyro
video. Here I present my algorithm for the 4D rotation that moves some
other slices into the top and bottom positions. I describe in detail how to
look at this and how and why it works. My sequence is different from the
one in Melinda's introductory video and requires only five moves with no
"cleanup" moves.
- 03: 4:06 scramble
scramble I used for the solution. I'm using a previously posted method for
scrambling, but I describe from first principles why it is valid.
- 04: 7:59 blue green off corners
solution stage: moving all blue and green stickers off the corners. I also
introduce a few move patterns I use systematically throughout my solution.
- 05: 6:14 blue green to corners
solution stage: move all blue and green stickers back to the corners. It
turns out in this case to be all but one, which happens sometimes.
- 06: 5:02 solve blue
face starting from all the blue stickers on the outer corners.
- 07: 3:53 green except last corners
Solve green down to one pair of corners out of orientation such that one of
them can't be fixed using regular 3D Rubik's cube operations.
- 08: 4:08 final solve
solution, resolving the pair of non-oriented corners (or "disoriented", as
I say in the video), with a clear explanation of how my method works.
- 09: 6:00 corner monoflip demo
stand-alone video showing my algorithm for fixing the single corner
monoflip issue. My algorithm is 34 twists, counting twists of a half slice
(treating one face as a 3D Rubik's cube) as a single twist and counting the
gyro as zero. (One could argue that the half twist should count as two
because how it is justified, but I'm counting it as one here.)
- 10: 2:30 pair swap demo
video showing a common sequence I use to swap two pairs of corners. I use
this various times during the solution (contrary to what I say in the
video), but this video demonstrates it in an otherwise pristine puzzle,
making it easier to follow and understand.
Each video has a descrption with slightly more detail. I hope you enjoy
these. I'm looking forward to feedback and commentary.

Welcome back Jay!
Unknown to most of the list is the fact that without Jay, perhaps
none of this would have happened. Don and I had written the first
version of MC4D some 30 years ago, but were at an impasse. The
implementation was a bit of a mess, and neither of us wanted to
clean it up, nor open-source it in such a state. Jay came along and
said "I'll do that", and did the dirty work needed to sat=
isfy our
requirements and get it to build on Linux. His help was a godsend.
Regarding video series, the solution to making them play in order is
to create a playlist. You can reorder them, add descriptions, and
then just share the playlist link. I've added you to the 2x2x2x2 HO=
F
and linked to your scramble, but once you create a playlist I'll
link to that instead.
BTW, Jay's solution is #10, the first-10 solutions list is full. As

It's great to have you back, Jay!

in the 4 to 8 minute range. The videos are as follows:

rotation" video. Here I present my algorithm for the 4D
rotation that moves some other slices into the top and
bottom positions. I describe in detail how to look at this
and how and why it works. My sequence is different from
the one in Melinda's introductory video and requires only
five moves with no "cleanup" moves.
scramble I used for the solution. I'm using a previously
posted method for scrambling, but I describe from first
principles why it is valid.
solution stage: moving all blue and green stickers off the
corners. I also introduce a few move patterns I use
systematically throughout my solution.
solution stage: move all blue and green stickers back to
the corners. It turns out in this case to be all but one,
which happens sometimes.

Solve green down to one pair of corners out of orientation
such that one of them can't be fixed using regular 3D
Rubik's cube operations.
solution, resolving the pair of non-oriented corners (or
"disoriented", as I say in the video), with a clear
explanation of how my method works.
stand-alone video showing my algorithm for fixing the
single corner monoflip issue. My algorithm is 34 twists,
counting twists of a half slice (treating one face as a 3D
Rubik's cube) as a single twist and counting the gyro as
zero. (One could argue that the half twist should count as
two because how it is justified, but I'm counting it as
one here.)
video showing a common sequence I use to swap two pairs of
corners. I use this various times during the solution
(contrary to what I say in the video), but this video
demonstrates it in an otherwise pristine puzzle, making it
easier to follow and understand.

hope you enjoy these. I'm looking forward to feedback and
commentary.
