ProCGroups.FiniteStepSolvableQuotients
This module formalizes finite-step solvable quotients and their abelian actions.
AbelianActions
An action has no nontrivial fixed points if every globally fixed element is trivial.
Abelianization
This module develops finite quotient, subgroup, free pro-\(C\), generation, and cardinal-invariant constructions for profinite and pro-\(C\) groups.
Commutators
The topological closure of the abstract commutator subgroup.
