Theorem ax4 2195

Description: This theorem repeats sp 1759 under the name ax4 2195, so that the metamath program's "verify markup" command will check that it matches axiom scheme ax-4 2185. It is preferred that references to this theorem use the name sp 1759. (Contributed by NM, 18-Aug-2017.) (New usage is discouraged.) (Proof modification is discouraged.)
