% 8.01/1.86 | ALPHA: (function-axioms) implies:

% 8.01/1.86 | ALPHA: (input) implies:

% 8.01/1.86 |
% 8.01/1.86 | DELTA: instantiating (mixed_types_problem_17) with fresh symbol all_5_0 gives:

% 8.01/1.86 |
% 8.01/1.86 | ALPHA: (3) implies:

% 8.01/1.86 | (5) gives:
% 8.01/1.86 | (6) all_5_0 = 2
