  We present first measurable predictions for electromagnetic (two-photon)
double scattering production of two positron-electron pairs in ultraperipheral
heavy-ion collisions at LHC. Measureable cross sections are obtained with
realistic cuts on electron/positron (pseudo)rapidities and transverse momenta
for the ALICE and ATLAS or CMS experiments. The predictions for total and
differential cross sections are presented. We show also two-dimensional
distributions in rapidities of the opposite-sign (from the same or different
subcollisions) and of the same-sign ($e^+ e^+$ or $e^- e^-$) electrons and in
rapidity distance between them. Expected number of events are presented and
discussed. Our calculations strongly suggest that relevant measurements with
the help of ATLAS, CMS and ALICE detectors are possible in a near future.
