Proof step 176 from proof fix-bits2bytes-01 (previous step)

bits.first, # bits2bytes(bits) < n, # bits ≤ 8 * n ⊦ mklist(i2b(~1), n - # bits2bytes(bits)) + bits2bytes(bits) = bits2bytes(mklist(true, n * 8 - # bits) + bits), bits = [], # bits % 8 = 0 ∧ n * 8 ≠ # bits

User applied rule cut formula

And obtained the following new goals

Proof step 177:
n * 8 ≠ # bits, bits.first, # bits2bytes(bits) < n, # bits ≤ 8 * n ⊦ mklist(i2b(~1), n - # bits2bytes(bits)) + bits2bytes(bits) = bits2bytes(mklist(true, n * 8 - # bits) + bits), bits = [], # bits % 8 = 0 ∧ n * 8 ≠ # bits
Proof step 237:
bits.first, # bits2bytes(bits) < n, # bits ≤ 8 * n ⊦ n * 8 ≠ # bits, mklist(i2b(~1), n - # bits2bytes(bits)) + bits2bytes(bits) = bits2bytes(mklist(true, n * 8 - # bits) + bits), bits = [], # bits % 8 = 0 ∧ n * 8 ≠ # bits

Rule argument

fma: n * 8 ≠ # bits

Additional information
