The process e(+)e(-) --> Z gamma gamma - <q(q)over bar <gamma>gamma> is stu
died in 0.5 fb(-1) of data collected with the L3 detector at centre-of-mass
energies between 130.1 GeV and 201.7 GeV. Cross sections are measured and
found to be consistent with the Standard Model expectations. The study of t
he least energetic photon constrains the quartic gauge boson couplings to -
0.008 GeV-2 < a(0)/Lambda (2) < 0.005 GeV-2 and -0.007 GeV-2 < a(c)/Lambda
(2) < 0.011 GeV-2, at 95% confidence level. (C) 2001 Published by Elsevier
