Let x0 of type ι be given.
Apply unknownprop_85336ee07ace71a942dc508d3b8c851d9d6bb88511443b7dafbf11b71c263f4d with
λ x1 . ba9d8.. (616bf.. x0 x1) leaving 2 subgoals.
Apply unknownprop_0d2e8618ea244d22f7cc913b00fa77b277d9ba7cc6a18877e00000ded7fa2c79 with
x0,
λ x1 x2 . ba9d8.. x2.
The subproof is completed by applying H0.
