The Witt design and the extended binary Golay code in turn can be used to generate a faithful construction of the 24-dimensional Leech lattice Λ24, which is the subject of the second generation of seven sporadic groups that are subquotients of the automorphism of the Leech lattice, Conway group

  . There are five non-supersingular primes: 37, 43, 53, 61, and 67, all smaller than the largest of fifteen supersingular prime divisors of the friendly giant, 71. List of basic calculations
In decimal
5 is the only prime number to end in the digit 5 in decimal because all other numbers written with a 5 in the ones place are multiples of five, which makes it a 1-automorphic number.

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.
