Definition
A completely regular semigroup is a semigroup (i.e., a set with associative binary operation) where the subsemigroup generated by any element is a group under the induced multiplication.
Note that the identity elements for these groups need not, in general, coincide. If they do coincide, then the completely regular semigroup is a group.
