Bingo Card Lattices

When I first started out on my generalised diatonic stuff, I arranged my
grids like the Balzano (which is why they are like that in the PNM article).

I also laid them out like the bingo card lattice, as it does away with the
left-handed tonalities that Balzano mentions. But I draw my lattices in
other vectors that the prime vectors, and in all cases what operates
analogously to the 'minor third' structurally goes straight up, and the
'major third' goes down and off to the right at 120 deg.

the 19 and 31 systems can be arranged at least 2 ways each using either
square or haxagonal grids.
