1327

This number is a prime.

+ The prime whose difference to the next prime (1361) is such that the Cramer relation (pn+1 - pn)/log(pn)2 is the maximum for any prime greater than 113. [Ludovicus]

+ The number of named openings and variations listed in the second edition of The Oxford Companion to Chess by Hooper and Whyld.

+ If you relax the rules for bowling to allow any number of frames (not just ten), then the highest score you can have while having a prime score every frame, is 1327 (in the 59th frame). [Keith]

+ Your lowest chance of being born in a prime number year in the past millennium was to have been born in the 14th century (11 prime numbers, from 1301 to 1399, with a record gap between 1327 and 1361). [Tammet]

+ 1327 is the first prime number such that there is more than one multiple of 16 between it and the next prime (1361). Surprisingly, there are 3 multiples of 16 between 1327 and 1361 (1328, 1344, and 1360). [Jacobs]

+ The next prime number is 1361. The 34 prime number gap between 1327 and 1361 is the largest one between all consecutive prime numbers up to 9551. [Tsiagalakis]

+ "The Name of the Rose" is a debut novel by Italian author Umberto Eco. It is a historical murder mystery set in an Italian monastery in the year 1️⃣3️⃣2️⃣7️⃣. [Lewicki]

+ The century in the 1000's with the most primes is the 1400's with 17 primes. The century in the 1000's with the least primes is the 1300's with 11 primes. However, you might not expect that looking at the first few primes in each century. The 1300's starts out with a lot of primes. 1301, 1303, and 1307 are all prime. Then, there are some big gaps, like the record prime gap from 1327 to 1361. The 1400's has a slow start. 1409 is the first prime, followed by 1423. Then, there are a lot of primes, including the prime quadruplet 1481, 1483, 1487, 1489. It is like The Tortoise and the Hare. [Jacobs]
