While working on a nBAB for the number 43, MathBabbler noticed that 43 was a "twin prime" of number 41.

42 + 52 = 41 # sum of two squares 2 + 3 + 5 + 7 + 11 + 13 = 41 # sum of 1st six primes 11 + 13 + 17 = 41 # sum of three consecutive primes ??? adding up the sums of divisors for 1 through 7 yields 41 ???Another Wikipedia tidbit...
Euler first noticed (in 1772) that the quadratic polynomial P(n) = n2 + n + 41 is prime for all non-negative integers less than 40. The primes for n = 0, 1, 2, 3... are 41, 43, 47, 53, 61, 71... The differences between the terms are 2, 4, 6, 8, 10... For n = 40, it produces a square number, 1681, which is equal to 41 * 41, the smallest composite number for this formula. In fact if 41 divides n it divides P(n) too.MathBabbler created this nBAB when he was 51 years young. 51 in base-8 (octal) equals
