Query: Study of the reactions $e^+e^-\to\pi^+\pi^-\pi^0\pi^0\pi^0\pi^0$ and
  $\pi^+\pi^-\pi^0\pi^0\pi^0\eta$ at center-of-mass energies from threshold to
  4.5 GeV using initial-state radiation   We study the processes $e^+e^-\to\pi^+\pi^-\pi^0\pi^0\pi^0\pi^0\gamma$ and
$e^+e^-\to\pi^+\pi^-\pi^0\pi^0\pi^0\eta\gamma$ in which an energetic photon is
radiated from the initial state. The data were collected with the BaBar
detector at the SLAC National Accelerator Laboratory.
  About 7300 and 870 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
$e^+e^-\to\pi^+\pi^-\pi^0\pi^0\pi^0\pi^0$ and the
$e^+e^-\to\pi^+\pi^-\pi^0\pi^0\pi^0\eta$ cross sections are performed. The
contributions from $\omega\pi^0\pi^0\pi^0$, $\eta\pi^+\pi^-\pi^0$,
$\omega\eta$, and other intermediate states are presented. We observe the
$J/\psi$ and $\psi(2S)$ in most of these final states and measure the
corresponding branching fractions, many of them for the first time.
