The ground-state structures of small fullerenes below {ital C}{sub 70} were determined by tight-binding molecular-dynamics total energy optimization. An efficient simulated annealing scheme was used to generate closed, hollow, spheroidal cage structures for all even-numbered carbon clusters from {ital C}{sub 20} to {ital C}{sub 70}. As a general trend, fullerenes prefer geometries which separate the pentagonal rings as far apart as possible. Except for {ital C}{sub 60}, {ital C}{sub 70}, and {ital C}{sub 50}, most fullerenes have relatively low symmetries.
