I have in Mathematica a list of lists like this:
l={{1, 5, 9, 13, 17, 21, 25}, {2, 6, 10, 14, 18, 22, 26}, {3, 7, 11, 15,
19, 23, 27}, {4, 8, 12, 16, 20, 24}, {5, 9, 13, 17, 21, 25}, {6,
10, 14, 18, 22, 26}, {7, 11, 15, 19, 23, 27}, {8, 12, 16, 20,
24}, {9, 13, 17, 21, 25}}
There are many duplicates within the elements. For example, Element 1 has {1,5,9,13,17,21,25}, but the majority of these elements show up again in Element 5, {5,9,13,17,21,25}, and likewise with elements 2 and 7. Is it possible to remove the smaller lists with the duplicate entries?
