From: G.V.N. Newsgroups: sci.math Subject: What about 41? Date: 22 Mar 1996 12:17:32 GMT Personnally I like 41, because it helps me to teach about recursive and recursively enumerable properties: I show the students 41 is prime 41+2 = 43 is prime 43 + 4 = 47 is prime 47+6 = 53 is prime 53 +8 = 61 is prime 61+10 = 71 is prime 71+12 = 83 is prime 83 +14 = 97 is prime Usually at this point some students have enough and say ok, you'll get prime numbers
