Thus Frobby and Gfan complement each other, since Gfan does not do computations on monomial ideals (except that it can draw them in three dimensions). Gfan does output monomial ideals, which Frobby can then process further. It's funny - I had not explicitly thought about the fact that these programs compliment each other well, despite my good friend Anders N. Jensen (who is the author of Gfan) having been my office mate for a year. It must be because most non-random ideals that I've been dealing with have been produced by the program 4ti2.
