Theorem csbima12gALTVD 38616
Description: Virtual deduction proof of csbima12gALTOLD 38540. 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. csbima12gALTOLD 38540 is csbima12gALTVD 38616 without virtual deductions and was automatically derived from csbima12gALTVD 38616.
