Description: Implication form of sbcbii 3838. sbcbi 43300 is sbcbiVD 43637 without virtual deductions and was automatically derived from sbcbiVD 43637 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.) |
