Theorem suctrALTcfVD 41414
Description: The following User's Proof is a Virtual Deduction proof (see wvd1 41060) using conjunction-form virtual hypothesis collections. The conjunction-form version of completeusersproof.cmd. It allows the User to avoid superflous virtual hypotheses. This proof was completed automatically by a tools program which invokes Mel L. O'Cat's mmj2 and Norm Megill's Metamath Proof Assistant. suctrALTcf 41413 is suctrALTcfVD 41414 without virtual deductions and was derived automatically from suctrALTcfVD 41414. The version of completeusersproof.cmd used is capable of only generating conjunction-form unification theorems, not unification deductions. (Contributed by Alan Sare, 13-Jun-2015.) (Proof modification is discouraged.) (New usage is discouraged.)
