superior highly composite number holds The first are 2, 3, 2, 5, 2, 3, 7, ... . In other words, the quotient of two successive superior highly composite numbers is a prime number. Superior highly composite radices The first few superior highly composite numbers have often been used as radices, due to their high divisibility for their size. For example: Binary (base 2) Senary (base 6) Duodecimal (base 12) Sexagesimal (base 60) Bigger SHCNs can be used in other ways. 120 appears as the long hundred, while 360 appears as the number of degrees in a circle.
