Please disregard that idea! My mistake.
Numbers above 22 all have the "same value", which are blank.
So when we swap two blank locations, they are different, but give the same
general layout.
Therefore the size is too large for the number of possible layouts.
It's more like =PERMUT(64,22) = 9.03E+37
This requies different code. Sorry.
