Intersection-transitively central factor
BEWARE! This term is nonstandard and is being used locally within the wiki. [SHOW MORE]
This article defines a subgroup property: a property that can be evaluated to true/false given a group and a subgroup thereof, invariant under subgroup equivalence. View a complete list of subgroup properties[SHOW MORE]
Definition
A subgroup of a group is termed an intersection-transitively central factor if its intersection with any central factor of the whole group is also a central factor.
Formalisms
In terms of the intersection-transiter
This property is obtained by applying the intersection-transiter to the property: central factor

Trimness
This subgroup property is trim -- it is both trivially true (true for the trivial subgroup) and identity-true (true for a group as a subgroup of itself).
