Proof step 4 from proof bits2int-pos (previous step)

⊦ 0 ≤ bytes2int(bits2bytes(boolvar ' + bits0)) ↔ ¬ boolvar

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ # bits ≤ 8 → bits2bytes(bits) = i2b(bits2int(bits)) '
Proof step 6:
¬ #(boolvar ' + bits0) ≤ 8 ⊦ 0 ≤ bytes2int(bits2bytes(boolvar ' + bits0)) ↔ ¬ boolvar
Proof step 72:
#(boolvar ' + bits0) ≤ 8 ⊦ 0 ≤ bytes2int(i2b(bits2int(boolvar ' + bits0)) ') ↔ ¬ boolvar

Rule argument

name: bits2bytes-base rotate: F subst: [bits] → [boolvar ' + bits0]

Additional information

Used terms: boolvar ' + bits0
