Hi Andrey,

Can your technique be used to find non-orientable paintings? Maybe there

is a way to have the F_25 field give the 12-color {5,4} and a corresponding

{5,3,4} with much less than 130 colors?

In any case, I do still think VT, ET, and RT versions of a 2-color {5,3,4}

would be worthy and enjoyable puzzles.
