After having had a bad result from other Ronald L. Graham,Erdos on Graphs : His Legacy of Unsolved Problems, books and articles. I was surprised with this book. I think that Dr. Knuth seems to turn what he touches to gold? I kind of wish I had read this one several years ago whenI wasn't as familiar with the material.I was amazed to find the recursion for the Eulerian numbers of the second type and a host of very useful identities as well.
