Proof step 47 from proof bytes2bytes-fix (previous step)

¬ ( b2i(int2bytes(bytes2int(by0 ' + bytes)).first) < 0 ∧ # int2bytes(bytes2int(by0 ' + bytes)) < 2 + # bytes ∧ int2bytes(bytes2int(by0 ' + bytes)) ≠ []), b2i(by0) < 0, b2i(by0) < 0, ∀ bytes0. # bytes0 < #(i2b(~1) + by0 + bytes) → true → bytes0 = [] ∨ fix(# bytes0, int2bytes(bytes2int(bytes0))) = bytes0 ⊦ fix(2 + # bytes, int2bytes(bytes2int(by0 ' + bytes))) = i2b(~1) ' + by0 ' + bytes

Additional information

Used simplifier rules: bytes2bytes-first-neg: ⊦ b2i(int2bytes(bytes2int(by ' + bytes)).first) < 0 ↔ b2i(by) < 0;%int2bytes-empty: ⊦ int2bytes(i) ≠ [];% ⊦ ¬ m < n ↔ n ≤ m;% ⊦ (bytes + bytes0) + bytes1 = bytes + bytes0 + bytes1;% ⊦ i < j → (¬ ¬ j ≤ i ↔ false);% ⊦ ¬ i < j ↔ j ≤ i;
