Description: Axiom scheme of separation ax-sep 5223 derived from the axiom scheme of replacement ax-rep 5209. The statement is identical to that of ax-sep 5223, and therefore shows that ax-sep 5223 is redundant when ax-rep 5209 is allowed. See ax-sep 5223 for more information. (Contributed by NM, 11-Sep-2006.) Use ax-sep 5223 instead. (New usage is discouraged.) |
