Description: Implication form of sbcbii 3834. sbcbi 44125 is sbcbiVD 44462 without virtual deductions and was automatically derived from sbcbiVD 44462 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.) |
