Congruence solvability in finite Moufang loops of order coprime to three

Group Theory 2023-01-11 v1

Abstract

We prove that a normal subloop XX of a Moufang loop QQ induces an abelian congruence of QQ if and only if each inner mapping of QQ restricts to an automorphism of XX and u(xy)=(uy)xu(xy) = (uy)x for all x,yXx,y\in X and uQu\in Q. The former condition can be omitted when XX is 33-divisible. This characterization is then used to show that classically solvable finite 33-divisible Moufang loops are congruence solvable.
