A possible mistake in the definition?

[edit]

The article says "a perfect lattice (or perfect form) is a lattice in a positive definite real vector space, that is determined by the set S of its minimal vectors in the sense that there is only one positive definite quadratic form taking value 1 at all points of S." However, The minimal value is not necessarily 1. This should be changed to something saying that the it is the unique (positive-definite?) quadratic form taking the minimal value at all points of S.

Any objection?
