%N Number of degeneracies on the sets of N ordinary trees with p vertices.

%D Elena V. Konstantinova and Maxim V. Vidyuk, "Discriminating tests of information and topological indices. Animals and trees", J. Chem. Inf. Comput. Sci., (2003), vol. 43, 1860-1871. See Table 15, column 5 on page 1868.

%e If p=16 then the parameter H_lambda is 8094 which is the tenth term in the sequence. See the paper by Elena V. Konstantinova and Maxim V. Vidyuk for the definition of H_lambda.
