Query: A topologically induced 2-in/2-out operation on loop cohomology   We apply the Transfer Algorithm introduced in arXiv:1106.5090 to transfer an
A_\infty-algebra structure that cannot be computed using the classical Basic
Perturbation Lemma. We construct a space X whose (base pointed) loop cohomology
H = H^*(\Omega X; Z_2) comes equipped with a nontrivial operation \omega : H x
H --> H x H.
