Description:Two things were new to me:
1) the Fermat matrix
2) an Umbral Calculus expansion of the Eulerian numbers
I can't give the book fives stars because "the number of graphs or order k on n"
just doesn't seem to be something you can compute using his text.
For 1974 this was a very advanced text and he talks of a sequel
that I'm going to look for now!
This text is maybe one that Dover Books should reproduce
for students.
