Finite subgroups of \(\text{GL}_{24}(\mathbb{Q})\). (English) Zbl 0870.20029

The author provides a full list of maximal finite irreducible subgroups \(G\) of \(\text{GL}(n,\mathbb{Z})\) together with their \(G\)-lattices of minimal determinant. The information given is very precise, and contains such parameters as the determinant of the lattice and the number of vectors of minimal length. A \(G\)-invariant quadratic form is given for every primitive group \(G\).
