Theorem hhssabloilem 27502
Description: Lemma for hhssabloi 27503. Formerly part of proof for hhssabloi 27503 which was based on the deprecated definition "SubGrpOp" for subgroups. (Contributed by NM, 9-Apr-2008.) (Revised by Mario Carneiro, 23-Dec-2013.) (Revised by AV, 27-Aug-2021.) (New usage is discouraged.)
