Let x0 of type ι be given.
Let x1 of type ι be given.
Let x2 of type ι be given.
Let x3 of type ι be given.
Let x4 of type ι be given.
Let x5 of type ι be given.
Let x6 of type ι be given.
Let x7 of type ι be given.
Let x8 of type ο be given.
Apply H8 with
x0.
Apply andI with
SNo x0,
∃ x9 . and (SNo x9) (∃ x10 . and (SNo x10) (∃ x11 . and (SNo x11) (∃ x12 . and (SNo x12) (∃ x13 . and (SNo x13) (∃ x14 . and (SNo x14) (∃ x15 . and (SNo x15) (bbc71.. x0 x1 x2 x3 x4 x5 x6 x7 = bbc71.. x0 x9 x10 x11 x12 x13 x14 x15))))))) leaving 2 subgoals.
The subproof is completed by applying H0.
Let x9 of type ο be given.
Apply H9 with
x1.
Apply andI with
SNo x1,
∃ x10 . and (SNo x10) (∃ x11 . and (SNo x11) (∃ x12 . and (SNo x12) (∃ x13 . and (SNo x13) (∃ x14 . and (SNo x14) (∃ x15 . and (SNo x15) (bbc71.. x0 x1 x2 x3 x4 x5 x6 x7 = bbc71.. x0 x1 x10 x11 x12 x13 x14 x15)))))) leaving 2 subgoals.
The subproof is completed by applying H1.
Let x10 of type ο be given.
