Valence connectivity in molecular graphs is described by 10-tuples ij where ij denotes the number of edges connecting vertices of valences i and j. A shorter description is provided by 4-tuples containing the number of vertices and values of Randi}, Zagreb and modified Zagreb indices. Surprisingly, these two descriptions are in one-to-one correspondence for all acyclic molecules of practical interest, i.e., for all those having no more than 100 atoms. This result was achieved by developing an efficient algorithm that is linear in the number of 10-tuples.
