	Prime Curios!: 41
		It's one of the numbers p (or "Lucky Numbers of Euler") such that a Euler-like polynomial is prime for n = 0, 1,..., p - 2.
		The Heptagonal number (r(5r - 3)/2) created using the prime base number of r = 41, is a concatenation of itself, 4141.
		The prime number 41 is the record number of matches played by a player in an English cricket season (Bobby Abel in 1902).
