Proof step 649 from proof bitsand-cast (previous step)

# bits1 = 2 + # bits, # bits1 ≤ # bits2 + # bitsand(false ' + true ' + bits, bits1), # bits3 ≤ m, bits3.first, # bits1 ≤ # bitsand(false ' + true ' + bits, bits1) ⊦ m = 0, bits3 = [], mklist(false, m) + bitsand(bits1, false ' + true ' + bits) = lastn(2 + # bits + m, mklist(false, m) + bitsand(false ' + true ' + bits, bits1)), bits1 = [], bits2 + mklist(false, m) = [], bits3 + bits1 = []

User applied rule insert rewrite lemma

And obtained the following new goals

Rule argument

seq: ⊦ n = # bits → lastn(n, bits) = bits subst: [bits, n] → [mklist(false, m) + bitsand(false ' + true ' + bits, bits1), 2 + # bits + m] rotate: F spec: list-del inst: bitlista name: lastN-all

Additional information

Used terms: mklist(false, m) + bitsand(false ' + true ' + bits, bits1), 2 + # bits + m
