Hexagonal capping of symmetric cubic graphs
Hexagonal capping HC(G) has four vertices {u0, v0},{u0, v1},{u1, v0},{u1, v1} for each edge {u,v} of G, and each {u_i, v_j} is joined to each {v_j, w_(1-i)}, where u and w are distinct neighbors of v in G. The collection includes hexagonal capping of cubic symmetric graphs up to 798 vertices.
