Combinatorics | Math History | NJ Wildberger

Author: Insights into Mathematics

We give a brief historical introduction to the vibrant modern theory of combinatorics, concentrating on examples coming from counting problems, graph theory and generating functions. In particular we look at partitions and Euler’s pentagonal theorem, Fibonacci numbers, the Catalan sequence, the Erdos Szekeres theorem, Ramsey theory and the Kirkman Schoolgirls problem.

Screenshot PDFs for my videos are available at the website These give you a concise overview of the contents of the lectures for various Playlists: great for review, study and summary.

My research papers can be found at my Research Gate page, at

My blog is at, where I will discuss lots of foundational issues, along with other things.

Online courses will be developed at The first one, already underway is Algebraic Calculus One at Please join us for an exciting new approach to one of mathematics’ most important subjects!
