Hi Andrey,

Sorry for the delay. I was camping this weekend and disconnected from the

interwebs.

To find working values, I looked at your file and compared your coloring

configuration to the one for the hemidodecahedron. Two tags needed to be

changed:

- "UseMirroredEdgeSet" needed to be set to false. That is true by

default, but I’ve noticed it generally must be false for non-orientable

puzzles. - The hemidodec also had "EndRotation" = 1.

Here is a working file, which only differs from your file by those two tags:

http://www.gravitation3d.com/magictile/4d_cubing/%7B10,3%7D%206C%20edited.xml

I wanted to note that there was one required alteration to the

hemidodecahedron coloring config. The elliptic puzzle had "InitialEdgeSet"

= 1, but for the hyperbolic puzzle, this needed be left as the default

(initial reflections across all edges) so it could fill out the whole

plane. It is so interesting how the spherical puzzles can be expanded to

hyperbolic tilings.

Hope this helps!

Roice
