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

Induction Base:
sqr(gen_0':s:cons_sqr:cons_double:cons_+2_3(0)) ->_R^Omega(1)
0'

Induction Step:
sqr(gen_0':s:cons_sqr:cons_double:cons_+2_3(+(n1117_3, 1))) ->_R^Omega(1)
+'(sqr(gen_0':s:cons_sqr:cons_double:cons_+2_3(n1117_3)), s(double(gen_0':s:cons_sqr:cons_double:cons_+2_3(n1117_3)))) ->_IH
