Hi Melinda,

I can see {3,9}a 24-Color E0:1:0 is close, but not exact. There, an orbit can visit a triangle twice, from two directions, but not three times. I haven’t found a similar property on other {3,n} puzzles. But, for those puzzles where the faces are not equivalent, I cannot exclude them unless I have tried all the faces.

Can you reveal the answer now?

Nan
