  We summarize our recent work on gauge theories with two flavors of fermions
in the two-index symmetric representation: SU(2) gauge theory with adjoint
fermions, SU(3) with sextets, and SU(4) with ten-dimensional-representation
fermions. All three systems have beta functions smaller than their perturbative
value, approaching a fixed point near the expected two-loop zero. In all cases
the mass anomalous dimension is small, under 0.5.
