  We consider N = 2 superconformal field theory with following properties: a)
Coulomb branch operators have fractional scaling dimensions, b) there are exact
marginal deformations . The weakly coupled gauge theory descriptions are found
by decomposing 3d mirror into different components, and different
decompositions correspond to different duality frames. The gauge theory is
formed by gauging Argyres-Douglas matter, and we write down all duality frames
for several classes with infinite sequence of theories.
