• 228 can be written using four 4's:
228 is nontrivially palindromic in base 7.
228 is digitally balanced in base 2 and base 4, because in such bases it contains all the possibile digits an equal number of times.
228 is an esthetic number in base 4, because in such base its adjacent digits differ by 1.
It is a tau number, because it is divible by the number of its divisors (12).
228 is strictly pandigital in base 4.
228 is a nontrivial repdigit in base 7.
It is a plaindrome in base 7, base 8, base 10, base 13 and base 14.
It is a nialpdrome in base 3, base 4, base 7 and base 16.
It is a zygodrome in base 7.
It is an amenable number.
It is a pseudoperfect number, because it is the sum of a subset of its proper divisors.
228 is a wasteful number, since it uses less digits than its factorization.
228 is an evil number, because the sum of its binary digits is even.
The square root of 228 is about 15.0996688705. The cubic root of 228 is about 6.1091147443.
Subtracting from 228 its sum of digits (12), we obtain a cube (216 = 63).
Subtracting from 228 its product of digits (32), we obtain a square (196 = 142).
The spelling of 228 in words is "two hundred twenty-eight", and thus it is an aban number.
