Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

TOP(mark(cons(z0, z1))) → c32(TOP(cons(proper(z0), proper(z1))), PROPER(cons(z0, z1)))

(69) CdtRuleRemovalProof (UPPER BOUND(ADD(n^1)) transformation)

Found a reduction pair which oriented the following tuples strictly. Hence they can be removed from S.

TAKE(z0, mark(z1)) → c15(TAKE(z0, z1))

We considered the (Usable) Rules:none
