Enumeration of Unimodular Lattices
In this chapter we state explicit formulae for the Minkowski-Siegel mass constants for unimodular lattices. We give Niemeier’s list of 24-dimensonal even unimodular lattices, use the mass constant to verify that it is correct, and then enumerate all unimodular lattices of dimension n ≤ 23.
