This number is a prime. The largest known prime number that cannot be represented as the sum of less than nineteen fourth powers. The absolute value of n2 - 47n + 479 isn't composite for 0 < n < 47. [Wesolowski] The smallest prime that is the sum of first n consecutive Hoax numbers, (n=6), i.e., 22+58+84+85+94+136=479. [Loungrides] In the 611 distinct-digit squares only the digit 6 appears a prime number of times, appearing 479 times in the 4358 total digits. [Gaydos] The first and last digit of 479 is 7 squared. If we repeat with the digits of 479 we obtain the prime 146479891. Will this procedure work again with 146479891? [Petrov] The pair of consecutive primes (479, 487) is the only pair, at least up to 10^9, of consecutive primes (p,q) such that the reverse of the digits of p is equal to 2*q. [Galliani] An 11-smooth number has only prime factors 2, 3, 5, 7, or 11. 479 is the smallest prime which is not the sum of two 11-smooth numbers. [Drost]
