Proof step 7 from proof int2bytes-shortval (previous step)

128 ≤ s2i(sho), 0 ≤ s2i(sho), 2 < # int2bytes(s2i(sho)), 0 < s2i(sho), s2i(sho) < 256 ⊦

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
0 ≤ i, 2 ^ (8 * i) ≤ j, j < 2 ^ (8 * (i + 1) - 1) ⊦ # int2bytes(j) = i→n(i + 1)
Proof step 6:
¬ (0 ≤ 1 ∧ 2 ^ (8 * 1) ≤ s2i(sho) ∧ s2i(sho) < 2 ^ (8 * (1 + 1) - 1)), 128 ≤ s2i(sho), 0 ≤ s2i(sho), 2 < # int2bytes(s2i(sho)), 0 < s2i(sho), s2i(sho) < 256 ⊦
