Proof step 26 from proof int2bits-2pot-04 (previous step)

mklist(false, i→n(i)) = boolvar ' + bits, 0 < i, 0 < 2 ^ i, j < 2 ^ i, j < 0, j + 1 < 2 ^ i, j < i, j * 2 ^ i < i, j + 1 < i ⊦ sgn(bitsinvert(uint2bits(~ j)) +1 + boolvar ' + bits) = int2bits(j) + boolvar ' + bits, j = 0, i = 0, (¬ boolvar) ∈ bitsinvert(uint2bits(~ j)) +1

User applied rule cut formula

And closed the goal!

Rule argument

fma: boolvar

Additional information

Used simplifier rules: ⊦ ¬ true ∈ bits +1 ↔ false;% ⊦ i + j + i0 = (i + j) + i0;% ⊦ i + j = j + i;% ⊦ boolvar ' + bits = bits0 → boolvar ∈ bits0; (forward)% ⊦ (bits + bits0) + bits1 = bits + bits0 + bits1;% ⊦ ¬ true ∈ mklist(false, n); Used formulas: boolvar
