Abstract
Infinite Steiner quasigroups, that is, commutative idempotent groupoids satisfying the identity (xy)x=y, form an almost universal category. As a consequence, every monoid is representable by all nonconstant endomorphisms of a Steiner quasi-group, and there is a proper class of nonisomorphic representations of this kind. Similar results are obtained for partial Steiner quasigroups as well as for partial and complete Steiner triple systems naturally corresponding to these algebras.
