title: Polytetrahedral clusters.
abstract: By studying the structures of clusters bound by a model potential that favors polytetrahedral order, we find a previously unknown series of "magic numbers" (i.e., sizes of special stability) whose polytetrahedral structures are characterized by disclination networks that are analogous to hydrocarbons.
