Thread: "first IRP"

I have solved my first IRP.
IRP {6,6} 4-Color E0.7:0:0 Baumann Eduard 04/08/12 107 twists
Ed=20=20

Hey, congratulations, Ed!
I guess we need a new wiki hall-of-fame for IRP records. I'm just not
sure where it should go. Roice, what do you think?

BTW, Roice and I are recently back from the prestigious Gathering for
Gardner conference where I gave a talk on IRPs. I was very nervous but
about half way in I hit my stride. I explained these little-known
objects and how they relate to the Platonic solids. Only at the end did
I show that these objects are also twisty puzzles, and that really wowed
the crowd. Hopefully we will pick up some more members interested in
these and all the other wonderful twisty puzzles we now support.

Yes, nicely done Ed :) The density of that one seems like it would be
challenging to deal with.

The IRPs are listed in this section of the MagicTile records
pagein
the wiki. It might be nice to move them to their own page at some
point, as that page feels pretty unwieldy. But in the meantime, at least
there is a spot to record IRP solutions.

seeya,
Roice

Ah yes, thanks Roice.
I agree that the MT page is unwieldy. (More than 10 pages for its table
of contents alone!) That's a direct result of your success for creating
600 amazing new puzzles! I would love to see someone break that into
several new pages, one for each top-level puzzle type that MT supports.
I also think that it is begging for some screen shots. I added one for
the edge turning 4-color {6,6}
that
Nan and now Ed have solved. I hope that list members will add more.
Please consider adding a screen shot for each puzzle solution that you
enter that doesn't already have one. It sure will look nice once most
puzzles have pictures.

Hi Roice,

I played in IRP. When I reopen the saved File then I'm automatically in a h=
yperbolic view. I cannot change to the IRP view.

For all IRP (when not reopened) and for Skew Polyhedra it is possible to ch=
ange to the hyperbolic view (both: Poincarr=E9 and Klein) with "Setting/Ske=
w Polyhedra (IRP and 4D)/Show as skew/ false" and reverse.

The inverse is not possible: start with a hyperbolic puzzle then change to =
the IRP or Skew.
Normally there is no overlapping. The more recent IRP puzzles avoid redunda=
ncy with the hyperpolic puzzles.
This is not allways the case. Example:=20
Skew Polyhedra / {4,4|3} 9c F 0:0:1 is equivalent to
Euclidian / Klein / {4,4} 9c F 0:0:1.

For some cases the visibility in IRP is not as easy as in the hypebolic vie=
w.

Regards
Ed

Hi Ed,

Thank you for the reports.

I am not able to reproduce the problem you mention. For example, if I open
the "eb-MT-irp-66-4c-E 0p7-0-0.xml" IRP file that you uploaded to the
group, it loads and shows as an IRP (as long as the setting "Show as Skew"
is set to true). Let's discuss further, but offline from the group, to see
if we can figure out what is happening for you.

It's true that the inverse is not generally possible. While all the IRP
puzzles have a hyperbolic representation, a random hyperbolic
tiling/coloring will not typically have an associated IRP. So please be
advised that the settings under the "Skew Polyhedra (IRP and 4D)" section
do not apply to any of the Spherical/Euclidean/Hyperbolic puzzles.

There is indeed a small amount of overlap at the moment, because of puzzles
I had already made before ever starting the IRP work. Another reason I
left those in for now is that my code doesn't yet support IRP puzzles with
mixed turning, so the {4,4} 9C puzzle in the Euclidean section has some
extra twisting options that the IRP version doesn't have. I do hope to
make this better in the future, and to remove the few duplicate
puzzles that are there.

Thanks again,
Roice
