Single Curio View:   (Seek other curios for this number)
The start of an extraordinarily large gap between primes in an arithmetic progression p+q*k, with q=152, where every positive integer k<357 yields composites. It's the first and yet only known gap that is both larger than q² and larger than phi(q)*(log (p+q*k))². [Raab]
