52 (fifty-two) is the natural number following 51 and preceding 53.
In mathematics
Fifty-two is the 6th Bell number[1] and a decagonal number.[2] It is an untouchable number, since it is never the sum of proper divisors of any number,[3] and it is a noncototient since it is never the answer to the equation x − φ(x).[4]
