OK. If the maxima commands stay as they are and the additional information
is not much more than one line per maxima statement, its ok. I'd be happy 
with that.

what I was afraid of is the following:

(Header skipped)

Notebook[{
Cell[BoxData[
    \(<< DiscreteMath`Combinatorica`\)], "Input",
  FontSize->14],

Cell[BoxData[
    \(Map[TableauxToPermutation[First[#], \ Last[#]]\  &,
      Flatten[Outer[List, Tableaux[{2, 1}], Tableaux[{2, 1}], 1],
        1]]\)], "Input",
  FontSize->14],

Cell[BoxData[
    \(Map[
      TableauxToPermutation[ConstructTableau[#],
          ConstructTableau[InversePermutation[#]]] &, \
      Permutations[{1, \ 2, \ 3}]]\)], "Input",
  FontSize->14],

Cell[BoxData[
    \(TableauxToMinor\ [t1_, t2_] := \ \[IndentingNewLine]Module[{d, \ x}, 
\
        d = Max[t1, \ t2];
        x\  = \ Array[
            y, {d, d}]; \[IndentingNewLine]\[IndentingNewLine]Product[
          Module[{m, s1, s2}, \[IndentingNewLine]s1 = \
              Partition[Complement[Range[d], Extract[t1, i]],
                1]; \[IndentingNewLine]s2\  =
              Partition[Complement[Range[d], Extract[t2, i]],
                1]; \[IndentingNewLine]m\  =
              Transpose[Delete[x, \ s1]]; \[IndentingNewLine]m =
              Delete[m, \ s2]; \[IndentingNewLine]Det[m]], {i,
            Length[t1]}]]\)], "Input",
  FontSize->14],

I think you get the picture.
