Mathimagics,

i had missed that last post. I knew that with gsf's program/grid collection you can list all automorph puzzle counts (and i told you so).

Thanks for your interesting summary. What i still don't clearly understand is, what happens to the multi-automorphism grids in Red Ed's/Jarvis table.

I think you should find the same grid in different classes, so isn't the sum more than all possible automorph grids ?

Ah, think i got it. This way they just reproduce the multi-automorph count correctly.
