Abstract. The results of our search for advanced helical (stellarator) systems
with a small number of field periods over the last five years are
presented. The comparison of stellarator systems with toroidal (helical or
axial) and poloidal directions of the contours with B = constant on the
magnetic surface as well as systems with Helias and Heliac-like orientation of
the magnetic surfaces cross-sections with respect to the principal normal to
the magnetic axis is undertaken. Particular attention is paid to some
attractive features of the systems with constant B-lines in the poloidal
direction.
