If you want to find a minimal length linear recurrence from a list of 
numbers you can use code posted at:

http://groups.google.com/groups?hl=en&lr=&safe=off&threadm=108qa91a2qimp77%40corp.supernews.com&prev=/groups%3Fnum%3D25%26hl%3Den%26lr%3D%26group%3Dsci.math.symbolic%26safe%3Doff%26start%3D450

I should point out that I have no reason to believe that code comprises 
the most efficient way to do this sort of thing.
