Description: The hypothesis of bj-df-cleq 32893. Note that the hypothesis of bj-df-cleq 32893 actually has an additional dv condition on and therefore is provable by simply using ax-ext 2602 in place of axext3 2604 in the current proof. (Contributed by BJ, 24-Jun-2019.) (Proof modification is discouraged.) |
