Strong Incompatability of Tribimaximal Mixing with Quark-Lepton   Complementarity
  Although tribimaximal mixing (TBM) and quark-lepton complementarity (QLC) are both compatible with experimental data within one standard deviation ($ 1 \sigma$), the TBM and QLC assumptions are mutually exclusive by $56 \sigma$.
