Theorem sbcbi 45113

Description: Implication form of sbcbii 3803. sbcbi 45113 is sbcbiVD 45449 without virtual deductions and was automatically derived from sbcbiVD 45449 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.)
