The rewrite sequence
mark(sieve(from(X133734_4))) →⁺ a__sieve(cons(mark(mark(X133734_4)), from(s(mark(X133734_4)))))

(11) RewriteLemmaProof (LOWER BOUND(ID) transformation)

Proved the following rewrite lemma:
mark(gen_0':s:from:cons:true:false:divides:filter:sieve:primes:head:tail:if2_0(n11_0)) → gen_0':s:from:cons:true:false:divides:filter:sieve:primes:head:tail:if2_0(n11_0), rt ∈ Ω(1 + n11₀)

Induction Base:
mark(gen_0':s:from:cons:true:false:divides:filter:sieve:primes:head:tail:if2_0(0)) →_R^Ω(1)
0'

Induction Step:
mark(gen_0':s:from:cons:true:false:divides:filter:sieve:primes:head:tail:if2_0(+(n11_0, 1))) →_R^Ω(1)
s(mark(gen_0':s:from:cons:true:false:divides:filter:sieve:primes:head:tail:if2_0(n11_0))) →_IH
s(gen_0':s:from:cons:true:false:divides:filter:sieve:primes:head:tail:if2_0(c12_0))

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