% 2.15/1.19  Assumed formulas after preprocessing and simplification: 
% 2.15/1.20  | (0)  ? [v0] :  ? [v1] : (f(v0, v0) = v1 &  ! [v2] :  ! [v3] :  ! [v4] :  ! [v5] : (v3 = v2 |  ~ (f(v5, v4) = v3) |  ~ (f(v5, v4) = v2)) &  ! [v2] :  ! [v3] : (v3 = 0 | v1 = 0 |  ~ (f(v0, v2) = v3)) &  ! [v2] : ( ~ (v1 = 0) |  ~ (f(v0, v2) = 0)))
% 2.23/1.23  | Instantiating (0) with all_0_0_0, all_0_1_1 yields:
% 2.23/1.23  | (1) f(all_0_1_1, all_0_1_1) = all_0_0_0 &  ! [v0] :  ! [v1] :  ! [v2] :  ! [v3] : (v1 = v0 |  ~ (f(v3, v2) = v1) |  ~ (f(v3, v2) = v0)) &  ! [v0] :  ! [v1] : (v1 = 0 | all_0_0_0 = 0 |  ~ (f(all_0_1_1, v0) = v1)) &  ! [v0] : ( ~ (all_0_0_0 = 0) |  ~ (f(all_0_1_1, v0) = 0))
% 2.23/1.24  |
% 2.23/1.24  | Applying alpha-rule on (1) yields:
% 2.28/1.24  | (2) f(all_0_1_1, all_0_1_1) = all_0_0_0
% 2.28/1.24  | (3)  ! [v0] :  ! [v1] :  ! [v2] :  ! [v3] : (v1 = v0 |  ~ (f(v3, v2) = v1) |  ~ (f(v3, v2) = v0))
% 2.28/1.24  | (4)  ! [v0] :  ! [v1] : (v1 = 0 | all_0_0_0 = 0 |  ~ (f(all_0_1_1, v0) = v1))
% 2.28/1.24  | (5)  ! [v0] : ( ~ (all_0_0_0 = 0) |  ~ (f(all_0_1_1, v0) = 0))
% 2.28/1.24  |
% 2.28/1.24  | Instantiating formula (4) with all_0_0_0, all_0_1_1 and discharging atoms f(all_0_1_1, all_0_1_1) = all_0_0_0, yields:
% 2.28/1.24  | (6) all_0_0_0 = 0
% 2.28/1.24  |
% 2.28/1.24  | From (6) and (2) follows:
% 2.28/1.24  | (7) f(all_0_1_1, all_0_1_1) = 0
% 2.28/1.24  |
% 2.28/1.24  | Instantiating formula (5) with all_0_1_1 and discharging atoms f(all_0_1_1, all_0_1_1) = 0, yields:
% 2.28/1.24  | (8)  ~ (all_0_0_0 = 0)
% 2.28/1.24  |
% 2.28/1.24  | Equations (6) can reduce 8 to:
