A winning solution to the 15-hole triangular peg solitaire game is: (4,1), (6,4), (15,6), (3,10), (13,6), (11,13), (14,12), (12,5), (10,3), (7,2), (1,4), (4,6), (6,1). The term (x,y) means move the peg in hole x to y. Not only does this solution leave the final peg in the original empty hole, but the sum of the peg holes in the solution is prime.
179 * 971 + 179 + 971 is prime (also emirp). No smaller emirp produces a prime in this manner. [Poo Sung]
'Prime numbers are what is left when you have taken all the patterns away. I think prime numbers are like life. They are very logical but you could never work out the rules even if you spent all your time thinking about them.' is a 179-letter quote from a book called The Curious Incident of the Dog in the Night-time by Mark Haddon. The quote also contains 43 words. All the chapters are numbered using prime numbers. [Homewood]
Between the beginning and the 179th digit of π, an equal number of five different decimal digits occur (there are 18 each of the digits 0, 3, 4, 5, and 9). Mike Keith conjectures this to be the last digit of π for which this happens (there are no others up to 10^9 digits).
