Be aware that when doing many comparisons the risk of a false-positive result increases.
In this case, there are 32 comparisons, you can thus expect the following amount of false-positive results:
  1.60 false positives, when considering a   5% risk acceptance (*, **, ***),
  0.32 false positives, when considering a   1% risk acceptance (**, ***),
  0.03 false positives, when considering a 0.1% risk acceptance (***)
