Theorem 2pm13.193VD

Description: Virtual deduction proof of 2pm13.193 . 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. 2pm13.193 is 2pm13.193VD without virtual deductions and was automatically derived from 2pm13.193VD .
