The factorisation conjecture for the twist element $F^*_{12,3}$
Let $X$ be the underlying finite set, let $F$ be the twist element, and let $\Delta$ be the coproduct on the associated algebra. Write $F^*_{12,3}$ for the element defined earlier…

Existence of a quasi-bialgebra with preantipode that is not quasi-Hopf
A quasi-bialgebra is an algebraic structure with coproduct, counit, and associator satisfying the quasi-bialgebra axioms; a preantipode is a map satisfying the three preantipode ax…
