The number 41 is a 13th smallest PRIME NUMBER. PRIME numbers are RARE. Yes there are many between say 1 and 200 (over 40 primes) but they quickly become rarer. Only 9592 primes between 1 and 100000. So while 41 looks ordinary sitting between ... "LIFE BEGINS at 40"... and " 42 SECRET TO LIFE AND EVERYTHING"... 41 is special. PRIME and PROUD 41 is the 13th smallest prime number. 41 is the sum of the first six prime numbers. 41 is the sum of two squares 16 and 25.

Twenty-three is the ninth prime number, the smallest odd prime that is not a twin prime. Twenty-three is also the fifth factorial prime,[1] the second Woodall prime.[2] It is an Eisenstein prime with no imaginary part and real part of the form 3n − 1. 23 is the third base-10 repunit prime exponent after 2 and 19.[3] The fifth Sophie Germain prime[4] and the fourth safe prime,[5] 23 is the next to last member of the first Cunningham chain of the first kind to have five terms (2, 5, 11, 23, 47). Since 14! + 1 is a multiple of 23 but 23 is not one more than a multiple 14, 23 is a Pillai prime.[6] 23 is the smallest odd prime to be a highly cototient number, as the solution to x − φ(x) for the integers 95, 119, 143, 529.[7] 23 is the firs...

31 is the number of regular polygons with an odd number of sides that are known to be constructible with compass and straightedge. 31 is the third Mersenne prime (25 − 1)[1] and the eighth Mersenne prime exponent, as well as the fourth primorial prime, and together with twenty-nine, a primorial prime, it comprises a twin prime. As a Mersenne prime, 31 is related to the perfect number 496, since 496 = 2(5 − 1)(25 − 1). 31 is also the 4th lucky prime[2] and the 11th supersingular prime.[3] 31 is a centered triangular number,[4] the first prime centered pentagonal number[5] and a centered decagonal number.[6] 31 is the eighth happy number.[7] For the Steiner tree problem, 31 is the number of possible Steiner topologies for Stein...
