Proof step 982 from proof bitsand-cast (previous step)

# bits = # bits1 ⊦ bits1 = lastn(# bits1, bits1), bits3 = [], bits1 = [], bits3 + bits = [], true ∈ 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] → [bits1, # bits1] rotate: F spec: list-del inst: bitlista name: lastN-all

Additional information

Used terms: bits1, # bits1
