Title: Decoupled molecules with binding polynomials of bidegree (n,2),
Abstract: We present a result on the number of decoupled molecules for systems binding
two different types of ligands. In the case of $n$ and $2$ binding sites
respectively, we show that, generically, there are $2(n!)^{2}$ decoupled
molecules with the same binding polynomial. For molecules with more binding
sites for the second ligand, we provide computational results.
