Popis: | We perform an asymptotic analysis of the distribution of points by degree and orbit size in trees whose points have maximum degree d ≥3. When d =4, these trees represent the carbon skeletons of alkanes. Tables are provided for d =3 and 4. These results are readily converted to corresponding conclusions for (1, d )-trees, whose points have only degree 1 or d . As an application we conclude with some speculations on the expected order of the automorphism group of a (1,4)-tree. |
