54 is a 19-gonal number. Twice the third power of three, 54 is a Leyland number. 54 can be written as the sum of three squares in three different ways: 7² + 2² + 1² = 6² + 2(3²) = 2(5²) + 2² = 54. It is the smallest number with this property. Like all other multiples of 6, it is a semiperfect number.
