Proof step 45 from proof byte-law-righthift-not (previous step)

# int2bits(128) = 1 + n, i2b(bits2int(sublist(0, n, int2bits(128)))) = i2b(bits2int(true ' + false ' + false ' + false ' + false ' + false ' + false ')) ⊦ n = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 46:
⊦ 0 ≤ i → int2bits(i) = uint2bits(i)
Proof step 47:
0 ≤ 128, # uint2bits(128) = 1 + n, i2b(bits2int(sublist(0, n, uint2bits(128)))) = i2b(bits2int(true ' + false ' + false ' + false ' + false ' + false ' + false ')) ⊦ n = 0

Rule argument

seq: ⊦ 0 ≤ i → int2bits(i) = uint2bits(i) subst: [i] → [128] rotate: F spec: int2bits inst: name: int2bits-pos
