Theorem 2pm13.193VD 39453
Description: Virtual deduction proof of 2pm13.193 39085. 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 39085 is 2pm13.193VD 39453 without virtual deductions and was automatically derived from 2pm13.193VD 39453. (Contributed by Alan Sare, 8-Feb-2014.) (Proof modification is discouraged.) (New usage is discouraged.)
