N2 - Using data samples collected with the BESIII detector at the BEPCII collider at six center-of-mass energies between 4.008 and 4.600 GeV, we observe the processes e+e−→ϕϕω and e+e−→ϕϕϕ. The Born cross sections are measured and the ratio of the cross sections σ(e+e−→ϕϕω)/σ(e+e−→ϕϕϕ) is estimated to be 1.75±0.22±0.19 averaged over six energy points, where the first uncertainty is statistical and the second is systematic. The results represent first measurements of these interactions.
