The first number n for which 15n-4, 15n-2, 15n+2 and 15n+4 are all composite, but 15n-14, 15n-8, 15n+8 and 15n+14 are all prime.
There are exactly 271 positive numbers that give larger numbers when you write out their English names and add the letters using the alphabet code, i.e., a = 1, b = 2, etc. [Hartley]
The smallest prime p such that (p - 1) and (p + 1) are each divisible by a cube greater than one. [Beedassy]
The longest of the three edges (271, 106, 103) of the smallest perfect parallelepiped. Note that the latter's shortest edge is also prime and, taken together with the middle edge, forms an emirp (106103). [Beedassy]
The smaller of only two primes less than a googol formed by concatenating in descending order the cubes of first n odd numbers, (case n=2). The other prime is for n=14. [Loungrides]
