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...
