A nice way to recolor the 10 sided cube is to give a side a quarter twist,
so it looks sort of like a baseball, and then make the (fairly) obvious
4 groups of 9 faces each in four colors, and two in-between stripes of 3
facies each. Each of the 9-facie groups will have 2 triangular facies, and
3 slant rectangular facies, and 4 squares. I think its a fairly simple
variation to solve, but I just made it last night and have not worked with
it much yet.
By the way, I just got my first magic tetrahedron. This one came from
Japan, but says made in Hongkong by "World-wide"(?) copyright by Meffert.
Anyone know who he is? It seems very similar to the one invented by
