Set of constitutional repeating units separated from the free valence of a dendron by the same number of constitutional repeating units.
Note: Generations are numbered consecutively starting from the constitutional repeating unit bearing the free valence.
Example of a four-generation dendron, highlighting constitutional repeating units of generations 1 to 4 and the end-groups. The preferred constitutional repeating unit is chosen such that the branch points are at its end in the dendron direction.
