A perfect pseudo-matching is a spanning subgraph in which every component is isomorphic to either K2 or K1;3. The study of packing problems on fullerene graphs is of particular interest due to their potential relevance in describing local bonding arrangements in carbon nanostructures. In this paper, we study the uniqueness of perfect star packing, and the existence of pseudo matchings in (2; 6)-fullerene graphs. Moreover, we show that the perfect starpacking in these graphs is unique. Furthermore, we introduced some perfect pseudo-matchings in (2; 6)-fullerene graphs.</p></abstract><kwd-group xml:lang="en"><kwd>(2</kwd><kwd>6)-Fullerene graphs</kwd><kwd>Perfect star packing</kwd><kwd>Perfect pseudo-matching.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">References</mixed-citation><mixed-citation xml:lang="en">References</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">T.
