(7) RewriteLemmaProof (LOWER BOUND(ID))
Proved the following rewrite lemma:

Induction Base:
mark(gen_0':nats:incr:cons:odds:s:pairs:head:tail2_0(0)) ->_R^Omega(1)
0'

Induction Step:
mark(gen_0':nats:incr:cons:odds:s:pairs:head:tail2_0(+(n76597_0, 1))) ->_R^Omega(1)
cons(mark(gen_0':nats:incr:cons:odds:s:pairs:head:tail2_0(n76597_0)), 0') ->_IH
cons(gen_0':nats:incr:cons:odds:s:pairs:head:tail2_0(c76598_0), 0')

We have rt in Omega(n^1) and sz in O(n). Thus, we have irc_R in Omega(n).
