Let x0 of type ι be given.

Let x1 of type ι → ι → 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_c9b23e671f24203ecb4e4923526160625cdf6a8afd63abb5013b61f4efe67b15 with 363b9.. x0 x1 x2 x3 x4, x0, x1, x2, x3, x4.

Let x5 of type ι → ι → ο be given.

Assume H0: x5 (363b9.. x0 x1 x2 x3 x4) (363b9.. x0 x1 x2 x3 x4).

The subproof is completed by applying H0.
