Here's a short story:

300 (three hundred) is the natural number following 299 and preceding 301. The number 300 is a triangular number and the sum of a pair of twin primes (149 + 151), as well as the sum of ten consecutive primes (13 + 17 + 19 + 23 + 29 + 31 + 37 + 41 + 43 + 47). It is palindromic in 3 consecutive bases: 300 = 606 = 454 = 363, and also in bases 13, 19, 24, 29, 49 and 59.
