We study the processes $e^{+} e^{-} \to 2 (π^{+} π^{-}) π^{0} π^{0} π^{0} γ$ and $2 (π^{+} π^{-}) π^{0} π^{0} η γ$ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14,000 and 4700 events, respectively, are selected from a data sample corresponding to an integrated luminosity of $469 {fb}^{- 1}$ . The invariant mass of the hadronic final state defines the effective $e^{+} e^{-}$ center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. From the mass spectra, the first ever measurements of the $e^{+} e^{-} \to 2 (π^{+} π^{-}) π^{0} π^{0} π^{0}$ and the $e^{+} e^{-} \to 2 (π^{+} π^{-}) π^{0} π^{0} η$ cross sections are performed. The contributions from $ω π^{+} π^{-} π^{0} π^{0}$ , $η 2 (π^{+} π^{-})$ , and other intermediate states are presented. We observe the $J / ψ$ and $ψ (2 S)$ in most of these final states and measure the corresponding branching fractions, many of them for the first time.
