We present the possible signatures appearing in general realizations of theMSSM based on 14 unrelated mass parameters at the SUSY scale. The parameters ofthe general MSSM are reduced by assuming a degeneracy of the sfermions of thefirst two generations with the same quantum numbers. We also assume nomass-splitting between neutral and charged Higgsinos. We do allow for separatesoft breaking terms for the third generation sfermons. We consider all possibleresulting $14! \approx 9 \cdot10^{10}$ relevant mass orderings and check forthe dominant decay cascades and the corresponding collider signatures. Indetermining the dominant decay modes we assume that mixing between sparticlesis sub-dominant. As preferred signatures, we consider charged leptons, missingtransverse momentum, jets, and $W, Z$ or Higgs bosons. We include also thecases of bi- and trilinear R-parity violation and show that specific signaturescan be used to distinguish the different scenarios.
