The spectrum for quasigroups with cyclic automorphisms and additional symmetries

Abstract

We determine necessary and sufficient conditions for the existence of a quasigroup of order $n$ having an automorphism consisting of a single cycle of length $m$ and $n-m$ fixed points, and having any combination of the additional properties of being idempotent, unipotent, commutative, semi-symmetric or totally symmetric. Quasigroups with such additional properties and symmetries are equivalent to various classes of triple systems.
