Proof step 14 from proof int2bytes-bytes2int-length-01 (previous step)

# bytes ≤ # sgn(bytes2bits(bytes)) / 8 ⊦ bytes = [], # sgn(bytes2bits(bytes)) % 8 = 0

User applied rule insert spec-lemma

And obtained the following new goals

Proof step 15:
⊦ ¬ # bits < # sgn(bits)
Proof step 16:
¬ # bytes2bits(bytes) < # sgn(bytes2bits(bytes)), # bytes ≤ # sgn(bytes2bits(bytes)) / 8 ⊦ bytes = [], # sgn(bytes2bits(bytes)) % 8 = 0

Rule argument

spec: bitopsaux inst: name: sgn-length seq: ⊦ ¬ # bits < # sgn(bits) subst: [bits] → [bytes2bits(bytes)] flags: []
