Abstract The bual and laub operations are defined and shown to be a useful means of analysing and coordinating previous descriptions of polyhexes. Some implications of a polyhex having a hole are explored. The position of such molecules in the Dias periodic table is argued. Formulae for moments of the Hückel energy in terms of graphical invariants are derived. The change in π-electron energy when a hole is formed is calculated for some molecules.
