Data for: Automatic synthesis of single and multi-degree-of-freedom planetary gear trains

The complete databases of non-fractionated planetary gear trains with 8-9 link and 1-3 DOFs are provided, as well as the databases of the corresponding parent graphs. For each parent graph, upper triangular elements of its adjacency matrix are stored. For each rotation graph or displacement graph of planetary gear train, upper triangular elements of its adjacency matrix, including the diagonal elements, are stored.
