Proved the following rewrite lemma:

Induction Base:
inf(gen_0':true:mark:false:nil:ok3_0(+(1, 0)))

Induction Step:
inf(gen_0':true:mark:false:nil:ok3_0(+(1, +(n19_0, 1)))) →_R^Ω(1)
mark(inf(gen_0':true:mark:false:nil:ok3_0(+(1, n19_0)))) →_IH
mark(*4_0)

We have rt ∈ Ω(n¹) and sz ∈ O(n). Thus, we have irc_R ∈ Ω(n).
