Proof step 13 from proof cast-mod-ls-most (previous step)

1 < i, 0 < i, i→n(i) ≤ 1 + i→n(i) -1 ⊦ bits2int(lastn(i→n(i), true ' + mklist(false, i→n(i) -1))) + 2 ^ (i - 1) = 0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 14:
i→n(i) ≤ 1 + (i→n(i) - 1), 1 < i, 0 < i ⊦ 2 ^ (i - 1) + bits2int(lastn(i→n(i), true ' + mklist(false, i→n(i) - 1))) = 0

Rule argument

Additional information

Used simplifier rules: ⊦ i < j ∧ 0 < i → 0 < j ∧ 1 < j; (forward)% ⊦ n -1 = n - 1;
