Description: A weak version of ralv 3219 not using ax-ext 2602 (nor df-cleq 2615, df-clel 2618, df-v 3202), but using ax-13 2246. For the sake of illustration, the next theorem bj-rexvwv 32866, a weak version of rexv 3220, has a dv condition and avoids dependency on ax-13 2246, while the analogues for reuv 3221 and rmov 3222 are not proved. (Contributed by BJ, 16-Jun-2019.) (Proof modification is discouraged.) |
