  It is natural to wonder how far the flat pattern in the distribution of
galaxies and clusters of galaxies around the de Vaucoueurs Local Supercluster
extends, and whether there are other similarly extended flat patterns in cosmic
structure. I present evidence of two extended flat sheet-like patterns in the
distributions of galaxies and clusters detected at redshifts less than 0.021.
Sheet A contains our position and is tilted 11 degrees from the supergalactic
pole, meaning the Local Supercluster is a moderately bent part of the more
extended Sheet A. The continuation of this sheet is detected in the disjoint
sample of galaxies at redshifts 0.021 to 0.041 and of galaxies and clusters of
galaxies at redshifts 0.042 to 0.085. Sheet B is 15 Mpc from us at its closest
point. It is detected at redshift less than 0.021 and at redshift 0.021 to
0.041. These results make a serious case for the reality of signatures of close
to flat extended sheet-like patterns.
