The newest results from the ATLAS Collaboration for the production of a
top-quark pair in association with a Z or W boson, and for the production
of four top quarks, are summarised in these proceedings. The measurements were
performed with 36.1 fbβ1 of proton-proton collision data from the Large
Hadron Collider at a centre-of-mass energy of 13 TeV.Comment: 7 pages, 3 figures, TOP2018 Conference Proceeding
