| Description: The complex numbers form a set. This axiom is redundant - see cnexALT 11828- but we provide this axiom because the justification theorem axcnex 9968 does not use ax-rep 4771 even though the redundancy proof does. Proofs should normally use cnex 10017 instead. (New usage is discouraged.) (Contributed by NM, 1-Mar-1995.) |
