Yes, thanks for the valuable hint.
The walk around (or better through) the whole 24cell is unnecessary complicated but is still an interesting and fascinating fact.

Hi Eduard,

Maybe I didn’t get you right but isn’t clicking on sticker c1 doing (c1)(c2,c3)? So if you have a permutation sequence X which intersects the cell of c1 with only one 3C piece, then the commutator

X, (clicking c1), X’, (clicking c1)

will flip two 3C pieces. Is this what you need?

But we must distinguish between turning (c1,c2,c3) and mirroring (c1)(c2,c3) in cycle notation. c1,c2and c3 are the three colors of an edge. Is that right (Nan, Andrey)? It is very difficult to imaging a walk so that an edge returns mirrored at home. I need such a walk to construct a mirroring macro for edges. Who wants help me?
