Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type ι → ι → ι be given.
Let x3 of type ι → ο be given.
Let x4 of type ι be given.
Assume H0:
x0 = 60b2c.. x1 x2 x3 x4.
Apply H0 with
λ x5 x6 . x4 = f482f.. x6 (4ae4a.. (4ae4a.. (4ae4a.. 4a7ef..))).
Let x5 of type ι → ι → ο be given.
The subproof is completed by applying unknownprop_1ebf33d9b27b653d6fc6f75947d3ca0be78ddccf29e0052751261b41f2a90711 with
x1,
eb53d.. x1 x2,
1216a.. x1 x3,
x4,
λ x6 x7 . x5 x7 x6.
