What? Nothing interesting about 331?! 331 is a prime number, cuban prime, sum of five consecutive primes (59 + 61 + 67 + 71 + 73), centered pentagonal number, centered hexagonal number, and Mertens function returns 0. 332. The sum of the first 332 primes is also prime. And there are 332 primes less than 10,000 that contain the digit 6. |
