Let x0 of type ι be given.

Let x1 of type ι be given.

Assume H0: 1ce4f.. x0 = 1ce4f.. x1.

Apply unknownprop_219a5692ece616b4a88502d80a85b644180cde982b21251f92a23d11d1a5d022 with x0, x1 leaving 2 subgoals.

Let x2 of type ι be given.

Assume H1: In x2 x0.

Apply H0 with λ x3 x4 : ι → ο . x3 x2.

The subproof is completed by applying H1.

Let x2 of type ι be given.

Assume H1: In x2 x1.

Apply H0 with λ x3 x4 : ι → ο . x4 x2.

The subproof is completed by applying H1.
