Peter: How long is the list? Don't know what you tried already but DeleteCases[Level[Outer[(If[(#1 - #2) ≤ - 10, {#1, #2}])&, Range[30], Range[10, 40]], {2}], Null] Range[30] is list 1 Range[10,40] is list 2 -10 is difference of list 1 and list 2 you want to set for equivalence relation test. Time this and see if it works for your list. Hans
