Let x0 of type ι be given.

Let x1 of type ι be given.

Assume H0: Subq x0 x1.

Let x2 of type ι be given.

Let x3 of type ι be given.

Assume H1: Subq x2 x3.

Apply unknownprop_e852c379a4d149a0e7c3983079d37ed9544b96fff7464ba0659bb4d1fa26edaf with x0, x1, λ x4 . x2, λ x4 . x3 leaving 2 subgoals.

The subproof is completed by applying H0.

Let x4 of type ι be given.

Assume H2: prim1 x4 x0.

The subproof is completed by applying H1.
