Something like this?
import Data.List
newList :: Int -> [[Int]] newList n = myNub [ l | l <- undefined -- not really sure how you want -- to generate these lists :) , sum l == sum [1..n] ]
myNub :: (Ord a) => [[a]] -> [[a]] myNub = nubBy (\a b -> sort a == sort b)

So I've checked out this code, and it doesn't compile on ghci. My version, without the "undefined" portion is(which still doesn't work): import Data.List newList :: Int -> [[Int]] newList n = myNub [ l | l <- [1..n], sum l == sum [1..n] ] myNub :: (Ord a) => [[a]] -> [[a]] myNub = nubBy (\a b -> sort a == sort b) Maybe there's something in the syntax that I'm not quite getting... \/\/
