I agree: your theorem is hard to prove because you don't have enough information about FA etc. Can you prove that mux_list_imp a b sel y ==> (LENGTH y = something) If you can't, why not adjust mux_list_imp's definition so that you can? Similarly, it would seem reasonable to have the same

[Hol-info] Existential quantifier length

Dear all Is it possible to specify length of bool list of the existential quantifier. I have following proof * (?FA FB FC.* * mux_list_imp (TL (num_BV_f (SUC (LENGTH y)) (BV_n (not_0 a) + 1))) a** F FA /\* * mux_list_imp (TL (num_BV_f (SUC (LENGTH y)) (BV_n (not_0 b) + 1))) b**
