The John-Teller effect of the giant fullerene (GF) is studied. We find
that in the giant fullerenes, the C-C bonds are dimerized, binding en
ergies are decreased, energy gaps are enlarged, and the symmetries are
reduced in the metallic GF but not in the semiconducting GF. The dime
rization patterns of these onions are presented. The distortions decre
ase as the number of carbon atoms on the GFs increases.
