Description: Implication form of sbcbiiOLD 37762. sbcbi 37770 is sbcbiVD 38134 without virtual deductions and was automatically derived from sbcbiVD 38134 using the tools program translate..without..overwriting.cmd and Metamath's minimize command. (Contributed by Alan Sare, 18-Mar-2012.) (Proof modification is discouraged.) (New usage is discouraged.) |
