Again, it's a message from Charlie Mckiz. He says that solve took just one =
week (27 hours by times) and 300K twists. My solve was longer (by time) - 1=
7 days (about 72 hours), but it was sub-100K :)

What can I say? The day 600-cell is solved, that's the end of the world. (i=
nspired by the recent 5/21/2011 judgment day prediction...)

My PC is not powerful enough to play the 600-cell. It takes a few seconds t=
o render a view. But the 120-cell seems acceptable, although not so smooth.=
I may try to experience this 120-cell someday. Maybe there's some hope tha=
t I can solve this one.

My sentiments exactly. Ridiculous! ...and I mean that in the best possible
way ;)

Like the {3,7}, the vertex-turning version will be a great deal
more tractable. I configured the two easiest possible vertex-turning
600-cells (by using your 120-cell and 600-cell puzzle data). One has only
trivial tips and one has cells sliced like gelatinbrain's 5.1.1. I'll put
them at the bottom of this email in case any would like to try them out.

Whereas the face-turning puzzle is borderline unusable on my computer,
these are both nice and smooth, and the pieces per cell not nearly as
scary. Of course, the number of cells still is! However, it might be
possible to solve the trivial tips version in a few hours, maybe even less
(120 tips at one tip per minute = 2 hours).

A large face-shrink and smaller sticker-shrink allows you to see the
stickers for a tip compacted together, which felt like it might be a good
way to approach a solve. Something like this
screenshot.
It doesn't work so well in practice though because you can't click pieces
towards the center (trying that always selects pieces from intervening
faces). I guess sticker-click twisting would be required to make these
particular display settings usable.

Cheers,
Roice

P.S. I agree with Melinda that it would be nice to be able to turn off the
cell borders sometimes.

Hi,

I've just solved the 600-cell VT with trivial tips, proposed by Roice. I st=
arted this puzzle a little bit right after Roice defined it.=20

I resumed it today when Melinda mentioned the 600-cell. It took me 1 hour a=
nd 24 minutes and 152 moves to solve the 120 trivial tips.=20

Since the vertex figure of the 600 cell is an icosahedron, solving each tip=
is nothing but reorienting an icosahedron. In many cases, the reorientatio=
n can be done using one multi-click move. But there's an exception: Althoug=
h one multi-click move can do a 72 deg rotation (5-cycle), it can't do a 14=
4 deg rotation. So I have to use more than 120 moves to solve the 120 tips.=
=20

Initially I thought that at the end when only one or two tips were unsolved=
, they were like needles in a haystack and I might not be able to find them=
. It turns out that's not a big problem. I only spent one or two minutes lo=
oking for them at the end.=20
