Let x0 of type ι be given. Let x1 of type ι be given. Assume H0: prim1 x1 (91630.. x0). Apply unknownprop_44132e34b8fcc92e54ff875d0e8f6137eeea7d41bb9d4b117dbbbb4d2f239782 with x1, x0, x0, x1 = x0 leaving 3 subgoals. The subproof is completed by applying H0. Assume H1: x1 = x0. The subproof is completed by applying H1. Assume H1: x1 = x0. The subproof is completed by applying H1. ■
