Assume H0: MetaNatTrans_buggy_strict x0 x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12.

Apply and5E with MetaCat x0 x1 x2 x3, MetaCat x4 x5 x6 x7, MetaFunctor x0 x1 x2 x3 x4 x5 x6 x7 x8 x9, MetaFunctor x0 x1 x2 x3 x4 x5 x6 x7 x10 x11, MetaNatTrans_buggy x0 x1 x2 x3 x4 x5 x6 x7 x8 x9 x10 x11 x12.

The subproof is completed by applying H0.
