Abstract:In this paper formulas of three types of the unordered partition of integer n in three Parts are obtained and a table of these formulas. is given We have discussed their applications on the O-graph, the generalized O-graph,the Alkanes,the Cyclanes with two links but having no branch, and so on.
Keywords:Unordered partition   0-graph. Generalized 0 - graph   Alkanes. Cyclones with two links but having no branch.
