Abstract: In spaces of constant curvature (= 1; elliptic, hyperbolic or generalized hyperbolic) the types of orthoschemes and the types of the Napiercycles are of interest. The aim is to calculate the numbers of these types for each dimension. This is possible with the help of a special theory for permutations, called geometric permutations and periodic permutations. The proofs for the concerning Lemmata are given in the appendix.

Keywords: Hyperbolic and elliptic geometries and generalizations, n-dimensional polytopes, orthoschems, permutations, Napier cycles, hyperbolic kernels
