  Gauge invariant extended configurations are considered for the three
fundamental (quarks) or adjoint (gluons) particles. For quarks it is shown that
the Y-shaped configuration is the only possible. For adjoint sources both the
Y-shaped and triangular configurations may realize. The corresponding static
potentials are calculated in the Method of Field Correlators and in the case of
baryon shown to be consistent with the lattice simulations. For adjoint sources
the potentials of Y-shaped and Delta-shaped configurations turn out to be close
to each other, which leads to almost degenerate masses of 3-- 3g glueballs and
odderon trajectories.
