Query: Energies of sp2 carbon shapes with pentagonal disclinations and
  elasticity theory   Energies of a certain class of fullerene molecules (elongated, contracted,
and regular icosahedral fullerenes) are numerically calculated using a
microscopic description of carbon-carbon bonding. It is shown how these results
can be interpreted and comprehended using the theory of elasticity that
describes bending of a graphene plane. Detailed studies of a wide variety of
structures constructed by application of the same general principle are
performed, and analytical expressions for energies of such structures are
derived. Comparison of numerical results with the predictions of a simple
implementation of elasticity theory confirms the usefulness of the latter
approach.
