Since the discovery of C60 over thirty years ago, the aesthetic beauty and high symmetry of fullerene cages as well as their possible use in medicine and alternative energies have created a flurry of interest and research into fullerenes and endohedral metallofullerenes. Fullerenes smaller than C60 have been particularly difficult to isolate, but the computed stability of certain isomers of C32 gives hope that smaller fullerenes can be found. We present a temperature dependent, statistical mechanical study of the possible isomers of C32, K@C32, Ca@C32 and Sc@C32 showing which isomers of each are most stable at a range of temperatures between 298.15 K and 6000 K.
