Seventeen is the 7th prime number. In Mathematics, a prime number (or a prime) is a Natural number which has exactly two distinct natural number Divisors 1 The next prime is nineteen, with which it forms a twin prime. 19 ( nineteen) is the Natural number following 18 and preceding 20. A twin prime is a Prime number that differs from another prime number by Two. 17 is the sum of the first four primes. 17 is the sixth Mersenne prime exponent, yielding 131071. In Mathematics, a Mersenne number is a positive integer that is one less than a Power of two: M_n=2^n-1 17 is an Eisenstein prime with no imaginary part and real part of the form 3n − 1.

17 is the third Fermat prime, as it is of the form $2^{2^2} + 1$, and it is also a Proth prime. In Mathematics, a Fermat number, named after Pierre de Fermat who first studied them is a positive integer of the form F_{n} = 2^{2^{ In Number theory, a Proth number is a number of the form P=k\ 2^n+1 where k is odd, n is a positive Since 17 is a Fermat prime, heptadecagons can be drawn with compass and ruler.

17 is known as the Feller number, after the famous mathematician William Feller who taught at Princeton University for many years. William (Vilim Feller né Vilibald Srećko Feller ( July 7 1906 &ndash January 14 1970) was a Croatian American Princeton University is a private Coeducational research university located in Princeton, New Jersey. Feller would say, when discussing an unsolved mathematical problem, that if it could be proved for the case n = 17 then it could be proved for all positive integers n. He would also say in lectures, "Let's try this for an arbitrary value of n, say n=17. "

Similar to Feller, Prof. Vadim Khayms of Stanford University was also known to use 17 as an arbitrary value during lectures. His Computational Mathematics Class would even include exactly 17 lectures.
