Query: Automorphism groups and normal forms in Normaliz   We discuss the computation of automorphism groups and normal forms of cones
and polyhedra in Normaliz, and indicate its implementation via nauty. The types
of automorphisms include integral, rational, Euclidean and combinatorial, as
well as algebraic for polytopes defined over real algebraic number fields.
Examples treated in detail are the icosahedron and linear ordering polytopes
whose Euclidean automorphism groups are determined.
