    As an accountant I would suggest...

    Range("A:A").Select
    ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Clear
    ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Add Key:=Range("A1"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
    With ActiveWorkbook.Worksheets("Sheet1").Sort
        .SetRange Range("A:A")
        .Header = xlNo
        .MatchCase = False
        .Orientation = xlTopToBottom
        .SortMethod = xlPinYin
        .Apply
    End With
    Range("C1").Select
    ActiveCell.FormulaR1C1 = "=RC\[-2\]"
    Range("C2").Select
    ActiveCell.FormulaR1C1 = "=COUNTIF(R\[-1\]C\[-2\]:R\[17\]C\[-2\],R\[-1\]C)"
    Range("C3").Select
    

    That that is accountants all over!

        Is this somehow related to the curious error page I received this morning from Web04? The one featuring ravenous hamsters obviously recovering from a three day methamphetamine/ethanol binge?

        The hamsters have asked for an end to the rumours and baseless allegations of alleged behaviour during certain incidents. The hamsters involved are currently taking some time off to spend more time with their families.

            Try this:

            #generation of the list
            import random
            sample = []; n=10; m = 100;rnd = random.Random();
            for it in range (1, m): sample.append(rnd.randint(1,n*m))

            #then
            sample.sort()
            print sample[:n]
            #boom

            @Chris - When are you planning to start supporting Python in the forum syntax highlighter? :-O [Edit] Not that I'm claiming that my little snippet is beautiful; far from it. I'm still way off being a full-blown Pythonista. But it sure would be nice to have it supported.

            Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Flat is better than nested. Sparse is better than dense. In the face of ambiguity, refuse the temptation to guess.

              My only other alternative is using this List.Sort overloaded method[^] but it would involve a more complex object and writing your own Compare method Scrap that idea Leppie has a great answer in my opinion[^]

                    Seems 'sort and take the first N' is the consensus on the algorithm, I think everyone's code does the same thing.

                            Well, if not, it is obviously possible to invent a language where one symbol does this operation :P. Since "sort and take" seems to be how to do it, it would be easy to conceive of a language where putting two symbols for "take" and "sort" next to each other would create a composite function that did it, making two characters the sensible theoretical minimum.

                                  Yeah exactly. Since I'm the first (i think) to propose it but I don't feel like spending 5 hours creating an interpreter, let's just pretend I'm the winner.

                                    I could easily modify my Rowan interpreter (what I posted my solution in) to implement sort as a single symbol, but it isn't worth it just for something like this :-\ . I don't allow composition of functions by juxtaposition like that though because it's confusing (see J).

                                        As an accountant I would suggest...

                                        Range("A:A").Select
                                        ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Clear
                                        ActiveWorkbook.Worksheets("Sheet1").Sort.SortFields.Add Key:=Range("A1"), SortOn:=xlSortOnValues, Order:=xlAscending, DataOption:=xlSortNormal
                                        With ActiveWorkbook.Worksheets("Sheet1").Sort
                                            .SetRange Range("A:A")
                                            .Header = xlNo
                                            .MatchCase = False
                                            .Orientation = xlTopToBottom
                                            .SortMethod = xlPinYin
                                            .Apply
                                        End With
                                        Range("C1").Select
                                        ActiveCell.FormulaR1C1 = "=RC\[-2\]"
                                        Range("C2").Select
                                        ActiveCell.FormulaR1C1 = "=COUNTIF(R\[-1\]C\[-2\]:R\[17\]C\[-2\],R\[-1\]C)"
                                        Range("C3").Select
                                        

                                        That that is accountants all over!

                                          APL:

                                          f←{⍺↑⍵⌷⍨⍋⍵}

                                          call like

                                          n f (sample vector)

                                          eg

                                          f←{⍺↑⍵⌷⍨⍋⍵}
                                          {f}
                                          xx←20?30 // 20 different ints in 1-30
                                          (23 28 14 12 10 8 15 3 2 7 26 4 20 29 24 30 25 18 21 27)
                                          10 f xx // smallest 10 values in xx
                                          (2 3 4 7 8 10 12 14 15 18)

                                          This is in my personal dialect since I don't have a licensed major APL on this machine, but the function is essentially the same in normal variants.
