 Four-spiral semigroup

A four-spiral semigroup is a mathematical concept that arises in the context of semigroup theory, a branch of abstract algebra. Semigroups are algebraic structures consisting of a set equipped with an associative binary operation. The term "four-spiral" typically refers to a particular class of semigroups characterized by certain properties, often used in the study of dynamical systems or the behavior of certain algebraic constructs.
