Proof step 13 from proof short-size (previous step)

16 < # int2bits(s2i(sho)), s2i(sho) ≤ 0, ~1 ≤ s2i(sho) ⊦ # int2bits(s2i(sho)) - 1 = 0

User applied rule cut formula

And obtained the following new goals

Rule argument

fma: ~1 = s2i(sho)

Additional information

Used simplifier rules: ⊦ i ≠ j → (i ≤ j ↔ i < j);% ⊦ ~1 < i ↔ 0 ≤ i;% ⊦ i ≤ j → (j ≤ i ↔ i = j);% ⊦ m < n → n ≠ 0; (forward)% ⊦ int2bits(0) = false ';% ⊦ # boolvar ' = 0 +1; Used formulas: ~1 = s2i(sho)
