I always rather liked line numbers (a-la 'can -n'). That also
makes discussion of the code easier:
1 import gmpy
2 i = 7
3 while i<100000:
4 # conjecture 1
5
6 if ((i % 3)>0) and ((i % 5)>0):
7 f = gmpy.fib(i)
8 ip = gmpy.is_prime(i)
9 fm = f % i
10 if (fm==(i-1)) and (ip==0):
11 print "fib %5d: %5d (mod %5d)" % (i,fm,i),
12 print gmpy.is_prime(i)
13 i += 2
14
15 """
16 Conjecture #1: if i ends in 3 or 7 and fib(i) == i-1 (mod i)
17 then i is prime
18
19 run #1 print all fib(i) == i-1 (mod i) that are composite
20
21 fib 5777: 5776 (mod 5777) 0 <-- counter example
22 fib 10877: 10876 (mod 10877) 0 <-- counter example
23 fib 17261: 17260 (mod 17261) 0
24 fib 75077: 75076 (mod 75077) 0 <-- counter example
25 fib 80189: 80188 (mod 80189) 0
26 """
Not sure what Google Groups does to it...
