After a lot of "research", I decided to go with $$ Problem-Solving \ Methods \ in \ Combinatorics \ by \ Pablo \ Soberon. We present a much broader and deeper exploration of challenging mathematics than a typical math curriculum and show students how to apply their knowledge and problem-solving skills to difficult problems. This 188-page book contains problems and solutions for 10 Junior Challenges (1997-2006), 10 Intermediate Challenges (1997-2006) and 9 Senior Challenges (1997-2005) in the United Kingdom. The three main challenges are: Junior Mathematical Challenge (UK year 8/S2 and below) Intermediate Mathematical Challenge (UK year 11/S4 and below) Senior Mathematical Challenge (UK year 13/S6 and below) [2] Introduction to Combinatorics UKMT will no longer be accepting cheques as a form of payment. Step 3: Practice Regularly: Consistent I am also running an online reading group on partition combinatorics for Gonville & Caius College, Cambridge. Claim: For a given placement of white counters, there are just as many arrangements with an even number of red counters as with an odd number of red counters.
