Fix generation of unique matrices for specific volume #1

Closed gepa71 closed 3 years ago

From https://oeis.org/A001001 :

These sublattices are in 1-1 correspondence with matrices

[a b d]
[0 c e]
[0 0 f]

with acf = n, b = 0..c-1, d = 0..f-1, e = 0..f-1. The sublattice is primitive if gcd(a,b,c,d,e,f) = 1.
