On the structure of generalized polyhedral semigroups with zero deficiency
Karim Ahmadidelir, H. Doostie, R. Gholami · Tamkang Journal of Mathematics · 2010
The polyhedral or triangle groups and some generalizations of them, such as binary polyhedral groups, have been studied by several authors. In this paper, we introduce two classes of semigroups that have the same presentation as these generalizations of polyhedral groups and investigate their structures, such as finiteness, their relationship with the groups presented by the same presentation.
