Proof step 7 from proof lsucc-01 (previous step)

n < 2 ^ log2 n ⊦ n = 0, log2(2 * n + 1) = log2 n + 1

User applied rule insert lemma

And obtained the following new goals

Proof step 8:
⊦ n ≠ 0 → ¬ n < 2^ log2 n
Proof step 9:
n ≠ 0 → ¬ n < 2^ log2 n, n < 2 ^ log2 n ⊦ n = 0, log2(2 * n + 1) = log2 n + 1

Rule argument

spec: inst: name: lls seq: ⊦ n ≠ 0 → ¬ n < 2^ log2 n subst: [n] → [n] flags: current, []
