I'm going a little off-topic on just benchmarking, but it's on-topic on
how cool Lua is.

The above is not the way experienced Lua programmers would code
it.  A move of the Rubik cube affects only 20 of the 54 little squares,
so you could represent it as a non-sequential table containing only
those, e.g.

m = {[3]=1,[6]=2,[9]=3,etc}

Then your loop becomes:

for x=1,54 do  cb[x] = ca[m[x] or x]  end
