Strings of numbers

Please excuse me, I'm neither a graduate nor a mathmetician, but I am a student. With a problem of sorts.

Possibly an interesting one.

I have a few thousand numbers. They're all muddled up. But the range is only 70 or so: at the moment they range from roughly -35 to +35. In these numbers, there are lots of strings of numbers that repeat. Possibly pretty ones. I'd like to find these repeated strings with a computer. Whats the longest string of numbers that repeats? Whats the most frequently repeated string of four or more numbers? The second most? Why can't excel tell me this? Or can it? What about SSPS?

e.g.

132546352542545351643214435221

If I can shoot aliens in 3D and build a railway from alaska to moscow, whay can't I find out that 254 comes up there twice?

Anyone?
