Hi everyone, (GSF?)

I'm back with a little questions

I a'm looking after the way to compute the number not the numbner itself

Thanks

To find the number of automorphisms of a solution grid, i.e. the number of ways of "scrambling" the grid back to itself, you can loop over all 648 ways of preserving a "base pattern" and make a note of which of those preserves the whole grid. For further information, see here.
