Abstract The isomers of tricyclic hydrocarbons CnH2n−4 having neither side chains nor multiple bonds have been classified into 12 classes from a graph theoretical point of view. We have also found an algorithm for deriving all the structures and the numbers of the isomers, and as an example, we show all the skeletons and the indices of the isomers in the class for C10H16 to which Adamantane belongs.
