Imagine you have your entire company of 𝑛 people who need to meet each outer on a 1:1 intro with everyone else. If you focus on one person you will see that they will take part in 𝑛−1 introductions. Since there are 𝑛 people, that would lead to 𝑛(𝑛−1) intros. Alice meeting Bob is the same as Bob meeting Alice making the number of introductions 𝑛(𝑛−1)/2.
