  We solve a conjecture on multiple nondegenerate steady states, and prove
bistability for sequestration networks. More specifically, we prove that for
any odd number of species, and for any production factor, the fully open
extension of a sequestration network admits three nondegenerate positive steady
states, two of which are locally asymptotically stable. In addition, we provide
a non-empty open set in the parameter space where a sequestration network
admits bistability.
