  We present a new method - called HINORA (HIgh-NOise RANdom SAmple Consensus)
- for the identification of regular structures in 3D point distributions.
Motivated by the possible existence of the so called Council of Giants, i.e. a
ring of twelve massive galaxies surrounding the Local Group in the Local Sheet
with a radius of 3.75 Mpc, we apply HINORA to the Local Volume Galaxy catalogue
confirming its existence. When varying the lower limit of K-band luminosity of
the galaxy entering the catalogue, we further report on the existence of
another ring-like structure in the Local Volume that now contains the Milky Way
and M31. However, this newly found structure is dominated by low-mass
(satellite) galaxies. While we here simply present the novel method as well as
its first application to observational data, follow-up work using numerical
simulations of cosmic structure formation shall shed light into the origin of
such regular patterns in the galaxy distribution. Further, the method is
equally suited to identify similar (or even different) structures in various
kinds of astrophysical data (e.g. locating the actual 'baryonic-acoustic
oscillation spheres' in galaxy redshift surveys).
