Divide Equally

Sort a list of random numbers into three lists of similar sum
//Sorting into three lists
nSrt=List.Reverse(List.Sort(n));
nSbL=List.Chop(nSrt,3);
lst1=List.Transpose(List.TakeEveryNthItem(nSbL,2,-1));
lst2=List.Transpose(List.Reverse((List.TakeEveryNthItem(nSbL,2,0))<1>));
//Three sublists with the sum of numbers more or less the same
lst3=(List.Transpose([List.Shuffle(lst1<1>),List.Shuffle(lst2<1>)]));
lst4 = List.Flatten(List.Clean(lst3,false)<1>,-1);
