Evagrius Ponticus considered
153 to represent a harmonization of contrasts, since 153 = 100 + 28 + 25, with 100 a square, 28 a triangle and 25 a circle.
Since
153 = 13 + 53 + 33, it is a 3-narcissistic number, and it is a Friedman number since
153 = 3 * 51. It is a Harshad number in base 10.
153 can also be written as 1! + 2! + 3! + 4! + 5!.
