Proof step 4 from proof uint2bits-2pot-05 (previous step)

0 ≤ i ⊦ uint2bits(i) = false ' + bits ↔ 2 ^ n→i(# bits) = i + 1, false ∈ bits

User applied rule case distinction

And obtained the following new goals

Proof step 5:
uint2bits(i) = false ' + bits, 0 ≤ i ⊦ 2 ^ n→i(# bits) = i + 1, false ∈ bits
Proof step 11:
2 ^ n→i(# bits) = i + 1, 0 ≤ i ⊦ uint2bits(i) = false ' + bits, false ∈ bits

Rule argument

pos: right 1
