Let x0 of type ι be given.
Let x1 of type ι be given.
Apply unknownprop_dec2978c0a72cebd51fcab0a380f03d4d80d1ccd8f826d378953148c305a60f0 with
x1,
x0,
Subq x0 x1 leaving 3 subgoals.
The subproof is completed by applying H1.
Apply H0 with
x0.
The subproof is completed by applying H2.
Assume H2: x0 = x1.
Apply H2 with
λ x2 x3 . Subq x3 x1.
The subproof is completed by applying Subq_ref with x1.
