Let x0 of type ι be given.

Let x1 of type (ι → ο) → ο be given.

Let x2 of type ι be given.

Apply unknownprop_604f6249a37733005212c6ef763cc1ef8c23f6bb41e288dc0decc301b50471be with 71057.. x0 x1 x2, x0, x1, x2.

Let x3 of type ι → ι → ο be given.

Assume H0: x3 (71057.. x0 x1 x2) (71057.. x0 x1 x2).

The subproof is completed by applying H0.
