  Four top quark production is a rare standard model process that has been
observed for the first time in proton-proton collisions at \sqrts at the CERN
LHC by both the ATLAS and CMS Collaborations. Both observations were made in
the same-sign dilepton and multilepton final states of the process and are
presented in this contribution. In addition, another measurement of four top
production by the CMS Collaboration using the all hadronic, one lepton and
opposite-sign dilepton final states is presented. This is the first result to
take a direct look at the all hadronic final state.
