+plantri and fullgen are programs for generation of certain types of planar graph
+The authors are Gunnar Brinkmann (University of Ghent) and
+Brendan McKay (Australian National University).
+
+Graphs are generated in such a way that exactly one member of each isomorphism
+class is output without the need for storing them. The speed of generation
+is more than 1,000,000 graphs per second in many cases, so extremely large
+classes of  graph can be exhaustively listed

-Symmetrica is a collection of routines, written in the programming language
-C, through which the user can readily write his/her own programs. Routines
-which manipulate many types of mathematical objects are available. Their use
-is facilitated by Symmetrica's object oriented style.
+Symmetrica is a library for combinatorics. It has support for the
+representation theory of the symmetric group and related groups, combinatorics
+of tableaux, symmetric functions and polynomials, Schubert polynomials,
+and the representation theory of Hecke algebras of type A_n.
