202 (two hundred [and] two) is the natural number following 201 and preceding 203.

In mathematics[edit]

202 is both a nontotient and a noncototient, meaning that there are no solutions to the equations φ(x) = 202 nor x - φ(x) = 202, with φ(x) being Euler's totient function.

202 is a Smith number in base 10, because its factorization is 2 × 101, and 2 + 0 + 2 = 2 + 1 + 0 + 1 = 4.
