Wikipedia:Articles for deletion/253 (number)
As a figurate number, it is the ninth centered heptagonal number http://oeis.org/A069099, the eighth centered enneagonal number http://oeis.org/A060544, the seventh star number http://oeis.org/A003154, the first nontrivial triangular number that is also centered heptagonal http://oeis.org/A253880 and the first nontrivial triangular star number http://oeis.org/A006060. It is also very early on the list of numbers of 5-packed words, whatever those are http://oeis.org/A243666, early on the list of third differences of eighth powers http://oeis.org/A255182, and early on the list of numbers of 5-multiparking functions, whatever those are http://oeis.org/A243687. A 3x3x3 grid has exactly 253 lines through pairs of points http://oeis.org/A222267. I think that's enough somewhat-interesting and varied properties to pass otability (numbers). This is despite the fact that I disagree with the nominator in the other direction about moderate-sized primes being notable by themselves; there are lots of primes, so I don't think primality alone is enough for notability
