  A search has been performed for pair-produced resonances decaying into three
jets. The proton-proton collision data used for this analysis were collected
with the CMS detector in 2016 at a center-of-mass energy of 13 TeV and
correspond to an integrated luminosity of 35.9 fb$^{-1}$. The mass range from
200 to 2000 GeV is explored in four separate mass regions. The observations
show agreement with standard model expectations. The results are interpreted
within the framework of $R$-parity violating SUSY, where pair-produced gluinos
decay to a six quark final state. Gluino masses below 1500 GeV are excluded at
95% confidence level. An analysis based on data with multijet events
reconstructed at the trigger level extends the reach to masses as low as 200
GeV. Improved analysis techniques have led to enhanced sensitivity, allowing
the most stringent limits to date to be set on gluino pair production.
