27442 is a product of 2 and a 4k+1 prime. Therefore it can be expressed as a sum of two squares in one way only viz. 161^2 + 39^2.

27442 is a number that is the greater of a pair of adjacent composite numbers such that both are only one step away from their home primes. Here 27441 --> 333049 and 27442 = 2 * 13721 --> 213721.

27442 has a so-called Lucky Cube because its cube contains the digit sequence “888”. See Bespoken for Sequences entry.
