Proof step 34 from proof BertrandsPostulate (previous step)

¬ i ≠ 2, 0 < i, i ≤ 2 ⊦ ∃ j. prime(j) ∧ i < j ∧ j ≤ 2 * i

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 35:
⊦ ∃ j. prime(j) ∧ 2 < j ∧ j ≤ 4

Rule argument

Additional information

Used simplifier rules: commutativity: ⊦ i * j = j * i; from specification int-mult%associativity: ⊦ i * j * j0 = (i * j) * j0; from specification int-mult
