Re: [math-fun] A family of lattices including both FCC, BCC, and a new(?) lattice

      The new lattice appears to be "integral," that is, all interpoint distances,
when squared, are integer multiples of the nearest-neighbor squared distance.

(Though I admit, I only checked a few distances.)

Can you compute its "theta series"?
