It is difficult to identify a G-C fullerene directly from its dimensions as
its lattice is not proportional to that of its archetype in general, although
they have the same three-dimensional shape. In this paper, the area scale
factor of a G-C fullerene is proved to be an integer, which can be calculated
from its dimensions. All the G-C transformations are k-inflations that can be
easily identified and inversed, primary transformations whose area scale
factors are prime numbers, or composite transformations whose area scale
factors are the product of those of its sub-transformations. As the result, a
method to identify any G-C fullerenes according to the area scale factor was
presented.Comment: 6 pages, 3 figure
