Query: Hecke actions on certain strongly modular genera of lattices   We calculate the action of some Hecke operators on spaces of modular forms
spanned by the Siegel theta-series of certain genera of strongly modular
lattices closely related to the Leech lattice. Their eigenforms provide
explicit examples of Siegel cusp forms.
