Apply unknownprop_1db1571afe8c01990252b7801041a0001ba1fedff9d78947d027d61a0ff0ae7f with λ x0 . True, λ x0 . x0, HomSet leaving 3 subgoals.
Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type ι be given.
Assume H0: True.
Assume H1: True.
Assume H2: HomSet x0 x1 x2.
The subproof is completed by applying H2.
Let x0 of type ι be given.
Assume H0: True.
The subproof is completed by applying lam_id_exp_In with x0.
