Sports
The Olympic Games have five interlocked rings as their symbol, representing the number of inhabited continents represented by the Olympians (Europe, Asia, Africa, Australia and Oceania, and the Americas). In AFL Womens, the top level of womens Australian rules football, each team is allowed 5 "interchanges" (substitute players), who can be freely substituted at any time. In baseball scorekeeping, the number 5 represents the third basemans position. In basketball:
The number 5 is used to represent the position of center. Each team has five players on the court at a given time. Thus, the phrase "five on five" is commonly used to describe standard competitive basketball. The "5-second rule" refers to several related rules designed to promote continuous play. In all cases, violation of the rule results in a turnover. Under the FIBA (used for all international play, and most non-US leagues) and NCAA womens rule sets, a team begins shooting bonus free throws once its opponent has committed five personal fouls in a quarter.

  , the largest of all five exceptional groups, also contains the other four as subgroups and is constructed with one hundred and twenty quaternionic unit icosians that make up the vertices of the 600-cell. There are also five solvable groups that are excluded from finite simple groups of Lie type. The five Mathieu groups constitute the first generation in the happy family of sporadic groups.
