da pinky finger numy Gender: Female Gimmick: Forty-Seven is a prime, and she loves pink. She gets figured out in the Five Fingers Club founded by Five (No, this is NOT a club for multiples of 5). She's even a professional harp player.
(c) Numberblocks What is the "Five Fingers" Club, you may ask? It is a club originally made by JingzheChina (Credit to them) that is a finite club, which contains only five members. This club is based on A352057 in OEIS. Apply the iteration An+1 = 2An+1 to A1 = 2, and the first five terms are all primes, while the prime property cannot insist for so long when apply to other prime initial values --- until 89. Thus the finite sequence may have some meanings. Since this club contains only five members which accords with the number of Five, Five founds this club named by her five finger, where 2, 5, 11, 23 and 47 are the members of this club, each correspondent to each finger. 47 is for the pinky, which is where her personality is based on.
