Let x0 of type ι be given.

Let x1 of type (ι → ο) → ο be given.

Let x2 of type ι → ο be given.

Let x3 of type ι be given.

Let x4 of type ι be given.

Apply unknownprop_51d0f41238782a6108e64ceba42ff2fd3cbd3176c507ad0ae8bcf3a997e63f4d with 98165.. x0 x1 x2 x3 x4, x0, x1, x2, x3, x4.

Let x5 of type ι → ι → ο be given.

Assume H0: x5 (98165.. x0 x1 x2 x3 x4) (98165.. x0 x1 x2 x3 x4).

The subproof is completed by applying H0.
