This is probably not the best place to ask this question but maybe 
someone can point me in the right direction.

I have a set of 2-D data points. Is there an algorithm for selecting 
subsets of data points that have nearly equal spacing in one dimension. 
Here is a simple example:

 05,  19
 09,  12
 25,  77
 37,  25
 43,  46
 47,  12
 51,  22
 65,  18

Points 1,3,5 and 8 are a subset with spacing 20 (25-5), 18 (46-25), and 
22(65-43) in the 1st dimension.

Another sub-group is 1,3,6 and 8 with spacing 20 (25-5), 22 (47-25), and 
18 (65-47).
