Definition
A subgroup property is termed conditionally lattice-determined if, for any group , any lattice automorphism of the lattice of subgroups , and any subgroup of , satisfies if and only if satisfies .
The use of the qualifier conditionally is to contract with fully lattice-determined subgroup property, where we allow the ambient group to also vary.
