Theorem sbcim2gVD 37266
Description: Distribution of class substitution over a left-nested implication. Similar to sbcimg 3308. The following User's Proof is a Virtual Deduction proof completed automatically by the tools program completeusersproof.cmd, which invokes Mel L. O'Cat's mmj2 and Norm Megill's Metamath Proof Assistant. sbcim2g 36893 is sbcim2gVD 37266 without virtual deductions and was automatically derived from sbcim2gVD 37266.
