Theorem csbfv12gALTVD 29012
Description: Virtual deduction proof of csbfv12gALT 5740. The following User's Proof is a Virtual Deduction proof completed automatically by the tools program completeusersproof.cmd, which invokes Mel O'Cat's mmj2 and Norm Megill's Metamath Proof Assistant. csbfv12gALT 5740 is csbfv12gALTVD 29012 without virtual deductions and was automatically derived from csbfv12gALTVD 29012.
