Pre-primitive permutation groups

Marina Anagnostopoulou-Merkouri, Peter J. Cameron, Enoch Suleiman

A transitive permutation group $G$ on a finite set $Ω$ is said to be pre-primitive if every $G$ -invariant partition of $Ω$ is the orbit partition of a subgroup of $G$ . It follows t…

Computing finite index congruences of finitely presented semigroups and monoids

Marina Anagnostopoulou-Merkouri, Reinis Cirpons, James D. Mitchell +1

In this paper, we describe an algorithm for computing the left, right, or 2-sided congruences of a finitely presented semigroup or monoid with finitely many classes, and an alterna…
