This is it.

I found it. Kreher wrote a moebius demystified. I need to read it, understand it, then go to SAGE and see what is implemented. If it's not, do it myself.

Topics of interest:
  • Subgroup Lattice
  • Subgroups(as posets)
  • Some how the orbit counting lemma is involved
  • Applying the moebius inversion
  • Generalized $A_{t,k}$ matrices
  • (Covering Arrays in the Background)
