Wilf's "Snake Oil" Method Proves an Identity in The Motzkin Triangle
arXiv:1507.07660
Abstract
We give yet-another illustration of using Herb Wilf's Snake Oil Method, by proving a certain identity between the entries of the so-called Motzkin Triangle, that arose in a recent study of enumeration of certain classes of integer partitions. We also briefly illustrate how this method can be applied to general `triangles'.
