There are no official prerequisites for this course, though familiarity with combinatorics is assumed. Students should already be familiar with Catalan numbers, Ramsey Theorem, generating functions, Euler’s theorem on Eulerian paths, 3-connectivity of convex polytopes in R^3, Chebychev’s Inequality, Markov’s Inequality, and finite groups.
There are four main textbooks used for this class:

There are eight problem sets, each weighted equally for your grade. Collaboration is encouraged with a few simple rules. On every problem not more than four people can collaborate. Every student writes her/his own solution. For each problem, all collaborators should be listed.
There are no exams in this course.
The entire grade is based on the eight problem sets.
