Abstract
The class of finitely presented algebras over a field with a set of generators and defined by homogeneous relations of the form , where runs through a subset of the symmetric group of degree , is introduced. The emphasis is on the case of a cyclic subgroup of of order . A normal form of elements of the algebra is obtained. It is shown that the underlying monoid, defined by the same (monoid) presentation, has a group of fractions and this group is described. Properties of the algebra are derived. In particular, it follows that the algebra is a semiprimitive domain. Problems concerning the groups and algebras defined by arbitrary subgroups of are proposed.
