Abstract : We describe the defect structure of a tetrahedral close packed model. Defects appear as a hierarchy of interlaced disclination networks which form the locus of sites where the local order deviates from a perfect icosahedral environment. This defect structure is generated by an iterative process which gradually decreases the curvature of an ideal polytope model.

Keywords : disclinations noncrystalline state structure short range order noncrystalline sphere packings defect structure tetrahedral close packed model interlaced disclination networks icosahedral environment interactive process ideal polytope model
