Then V looks like a 2-dimensional plane in the 6-space with the points having the first four coordinates all zero. The lattice looks like the appropriate sublattice. Use elementary row operations on A, and see how V and the sublattice change accordingly. If there is any nontrivial notion of isomorphism type, a combination of row operations will reveal it.
