  Masses of baryons {3/2}^+ are calculated on the base of representations of
dynamical "pseudounitary" q-deformed algebra u(4,1)_q which provides necessary
breaking of the 4-flavor symmetry realized by the assumed q-algebra su(4)_q. It
is demonstrated that, contrary to the case of su(3)_q octet baryons {1/2}^+,
one and the same q-analog of mass relation for baryons {3/2}^+ from decuplet
embedded into 20-plet of su(4)_q follows from evaluations within all the
different admissible "dynamical" representations.
