Let x0 of type ι be given.
Apply unknownprop_78927d114a9e016b6fa814cd3cb647b02601a2956c15aa990b929c9491fbf104 with
1,
x0,
λ x1 x2 . minus_CSNo x0 = x2 leaving 3 subgoals.
The subproof is completed by applying unknownprop_33594f786441fb94cfa9c7be2034d88216fac0dbcbe9e223f18185e2cf6cb053.
The subproof is completed by applying H0.
