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]

This subgroup property is a finitarily tautological subgroup property: when the ambient group is a finite group, the property is satisfied.

Definition

Definition with symbols

A subgroup H of a group G is termed subpronormal if there exists an ascending chain:

H=H0H1Hn=G

such that each Hi is a pronormal subgroup of Hi+1.

Formalisms

In terms of the subordination operator

This property is obtained by applying the subordination operator to the property: pronormal subgroup

Transitivity

This subgroup property is transitive: a subgroup with this property in a subgroup with this property, also has this property in the whole group.
