Proof step 2 from proof inv-last-01 (previous step)

mklist(true, # bits) = bits, bitsinvert(bits).last ⊦ bits = []

Heuristic structural induction applied rule structural induction

And obtained the following new goals

Proof step 3:
mklist(true, # bits0) = bits0 ∧ bitsinvert(bits0).last → bits0 = [] ⊦ mklist(true, #(boolvar + bits0)) = boolvar + bits0 ∧ bitsinvert(boolvar + bits0).last → boolvar + bits0 = []

Rule argument

term: bits

Additional information

Used simplifier rules: bitlist freely generated by [], +;;
