Proof step 4 from proof bits2bytes-mklist-01 (previous step)

n0 < 8 ⊦ bits2bytes(mklist(false, m * 8) + mklist(false, n0)) = i2b(0) ' + mklist(i2b(0), m), n0 = 0

User applied rule cut formula

And obtained the following new goals

Proof step 5:
mklist(false, m * 8) + mklist(false, n0) = mklist(false, n0) + mklist(false, m * 8), n0 < 8 ⊦ bits2bytes(mklist(false, m * 8) + mklist(false, n0)) = i2b(0) ' + mklist(i2b(0), m), n0 = 0
Proof step 20:
n0 < 8 ⊦ mklist(false, m * 8) + mklist(false, n0) = mklist(false, n0) + mklist(false, m * 8), bits2bytes(mklist(false, m * 8) + mklist(false, n0)) = i2b(0) ' + mklist(i2b(0), m), n0 = 0

Rule argument

fma: mklist(false, m * 8) + mklist(false, n0) = mklist(false, n0) + mklist(false, m * 8)

Additional information

Used formulas: mklist(false, m * 8) + mklist(false, n0) = mklist(false, n0) + mklist(false, m * 8)
