Proof step 17 from proof bitsor-mklist-in (previous step)

mklist(boolvar0, n) + bits ≠ [] ∧ bits0 = true ', # bits0 = 1, ∀ bits, boolvar0, boolvar, n, bits1. # bits1 < 1 → true → n = 0 ∨ bits1 = [] ∨ (boolvar ∈ bitsor(mklist(boolvar0, n) + bits, bits1) ↔ boolvar ∈ bitsor(boolvar0 ' + bits, bits1)) ⊦ boolvar ∈ true ' ↔ boolvar ∈ bitsor(boolvar0 ' + bits, bits0), bits0 = [], n = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 18:
∀ bits, boolvar0, boolvar, n, bits1. # bits1 < 1 → true → n = 0 ∨ bits1 = [] ∨ (boolvar ∈ bitsor(mklist(boolvar0, n) + bits, bits1) ↔ boolvar ∈ bitsor(boolvar0 ' + bits, bits1)) ⊦ n = 0, mklist(boolvar0, n) + bits = [], boolvar ↔ boolvar ∈ bitsor(boolvar0 ' + bits, true ')

Additional information

Used simplifier rules: ⊦ boolvar ' ≠ [];% ⊦ boolvar ∈ boolvar0 ' ↔ boolvar ↔ boolvar0;% ⊦ # boolvar ' = 0 +1;
