It looks as if you might profit enormously by taking a look at Stephen
Wolfram's recent book, "A New Kind of Science", where this and similar
problems are painstakingly discussed. In particular, in p. 611 of the book
you have a plot of the Pascal triangle. The code used by Wolfram illustrates
the way Mathematica programming is used by the great gurus.
