Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type ι → ο be given.
Let x3 of type ι be given.
Let x4 of type ι be given.
Apply H0 with
λ x5 x6 . x2 x4 = decode_p (f482f.. x6 (4ae4a.. 4a7ef..)) x4.
Apply unknownprop_d7d39a6ae9dd573b529ad4d558553a3d5dfa88cfa249f628a74ae5b338307a3e with
x1,
1216a.. x1 x2,
x3,
λ x5 x6 . x2 x4 = decode_p x6 x4.
Let x5 of type ο → ο → ο be given.
Apply unknownprop_ffe6e40960e279c2bfdd5436564fb47b3416a2f4b47c7977262e0b5dc7ec2541 with
x1,
x2,
x4,
λ x6 x7 : ο . x5 x7 x6.
The subproof is completed by applying H1.
