Symbol-free definition

A subgroup property is said to satisfy the image condition if, under any surjective homomorphism, the image of a subgroup satisfying the property in the source group, again satisfies the property in the target group.

Definition with symbols

A subgroup property p is said to satisfy the image condition if whenever \phi:G \to K is a surjective homomorphism and H \le G satisfies property p in G, then \phi(H) satisfies property p in K.
