Complement[eall, , , ... ] gives the elements in eall which are not in any of the .
The list returned by Complement is sorted into standard order. Example: Complement[a,b,c,d,e, a,c, d].
Complement[eall, , ... , SameTest->test] applies test to each pair of elements in eall and the to determine whether they should be considered the same. See The Mathematica Book on the web: Section 1.8.8. See also: Intersection, Union.
