From Binomial to Trinomial Coefficients and Beyond
In [3 (Chapter 6, Part I), 5, and 6] we presented the binomial coefficients r n in a geometric, an algebraic, and a combinatorial framework, being much concerned with establishing interesting connections between their algebraic properties and geometric features of the Pascal Triangle.
