311 (number)

311 is the natural number after 310 and before 312.

In mathematics

311 is a twin prime with 313; an Eisenstein prime with no imaginary part and real part of the form $3n\; -\; 1$; a Gaussian prime with no imaginary part and real part of the form $4n\; -\; 1$; and a permutable prime with 113 and 131. It can be expressed as a sum of consecutive primes in three different ways: as a sum of three consecutive primes (101 + 103 + 107), as a sum of five consecutive primes (53 + 59 + 61 + 67 + 71), and as a sum of seven consecutive primes (31 + 37 + 41 + 43 + 47 + 53 + 59). 311 is a strictly non-palindromic number, as it is not palindromic in any base between base 2 and base 309.
