Moreover, at $\mstar<8\times10^7\msun$, only 1 (LGS 3) of the 51 satellites is star-forming, and at $\mstar<9\times10^5\msun$ \emph{all} 40 satellites are quiescent.  These near-unity quiescent fractions for satellites of the MW/M31 contrast strongly with the nearly \emph{zero} quiescent fraction observed for isolated (non-satellite) galaxies at $\mstar<10^9\msun$ \citep[][see Introduction]{Geha2012, Phillips2014}.  The only clear known exceptions are KKR 25 ($\mstar=1.4\times10^6\msun$) and KKs ($\mstar=2.3\times10^7\msun$, 3 ($\mstar=2.3\times10^7\msun$),  quiescent galaxies that are $\approx2\mpc$ from the MW/M31.
