摘要
Abstract
A semigroup is a chameleon if it is the reduct of both a finitely based involution semigroup and a non-finitely based involution semigroup.Presently,the smallest published example of a chameleon is of order eight.This article constructs two smaller examples:a semigroup of order seven and a monoid of order six.The latter turns out to be a smallest chameleon among monoids.关键词
