“…Moreover it is likely that a counter‐example similar to that above can be constructed in this context, establishing that and are indeed distinct. Proving analogues of Corollary and of the counter‐example above would require a generalization of [, Theorem 3.12], that is, that if is a ‐bialgebra, then and both admit natural ‐bialgebra structures. We suspect that this is the case, at least under reasonable conditions on the twisting morphism , but the proof is beyond the scope of this article.…”
