Circular Combinations

Circular combinations are a unique application of the counting principle that is important to know! Circle are not the same as a line because where the first person sits determines the order of everyone else! This is part of the Prelim Maths Extension 1 Syllabus from the topic Combinatorics: Working with Combinatorics. In this post, we will explore Permutations and combinations of Circular combinations.

Here we will learn to use factorial notation to describe and determine the number of ways different items can be arranged in a line or a circle.
