The diagrams, describing the process of forming mini-fullerenes of single carbon
atoms and carbon dimers, are suggested. The diagrams have much in common for different
fullerenes. Forming fullerenes incorporates several stages. In the first stage an initial reaction
- active single atom adds another atom and activates it. In its turn the second atom adds two
other atoms creating a chain reaction whereupon mutual turning of the covalent bonds
generated leads to folding and to giving rise further covalent bonds that results in fullerene
formation. Another way consists in the following. Here a reaction-active carbon dimer adds at
once two atoms which create two covalent pairs connected with the dimer. Thereafter the
chain reaction is going in two opposite directions similar to the previous case. In both cases
the process consists of several stages which differ, but the final configuration, due to folding,
is one and the same fullerene. We have constructed graphs for all the mini-fullerenes
considered. This approach simplify the analysis both the ways of fullerene forming and its
structure.
