Forty one - did you know how special 41 is?

Forty-one is the 13th smallest prime number. The next is forty-three, with which it comprises a twin prime. It is also the sum of the first six prime numbers (2 + 3 + 5 + 7 + 11 + 13), and the sum of three primes (11 + 13 + 17).

Forty-one is also the 12th supersingular prime, a Sophie Germain prime and a Newman–Shanks–Williams prime. 41 is the smallest Sophie Germain prime to start a Cunningham chain of the first kind of three terms, {41, 83, 167}. It is an Eisenstein prime, with no imaginary part and real part of the form 3n − 1. 41 is a Proth prime as it is 5 × 2 to the power of 3 + 1.

The number figures in the polynomial f(n) = n2 + n + 41, which yields primes for −40 ≤ n < 40. This is also called the lucky number of Euler Prime. It is the biggest of such primes.

Forty-one is the sum of two squares, 42 + 52. Adding up the sums of divisors for 1 through 7 yields 41.

41 is the smallest integer whose reciprocal has a 5-digit repetend. That is a consequence of the fact that 41 is a factor of 99999.

It is a centered square number


It is also the atomic number of niobium.

Happy Birthday Ron Beer Cheers

Thanks for the prime primer Ian, if aliens ever land in London you won't even need a TARDIS to communicate with them Lol.

Happy Birthday Ron! Thank goodness someone around here keeps up with them, or I'd miss them all.
Make sure you have some fun today. Kiss the wife, hug the kids and shout out a good ol' Yeehaaa for being alive! Hope you get to unwrap a toy too, not just new socks and a hot water bag.
Your friend, Rockin' Rusty

Oh, and Happy Birthday Ron.  To me, 41 only means too many years ago.
