Understandng the properties, formation and evolution of the cosmic web is one of the main tasks
in cosmology.
In my talk I introduce the largest structures in the cosmic web, and the compatibility
of these structures with the LCDM cosmolocigal model.
Namely, in the Local Universe the richest structures in the cosmic web are very rich galaxy superclusters
and their compelxes - the Sloan Great Wall and the BOSS Great Wall. Moreover,
rich galaxy clusters and superclusters form a quasiregular pattern with
two huge perpendicular planes with extent of several hundreds of megaparsecs,
the Local Supercluster plane and the Dominant supercluster plane.
The characteristic distance between superclusters in this pattern is 120 - 140 h(-1) Mpc
The origin of these patterns in the supercluster distribution
is not yet clear. I discuss whether the presence
of such structures can be explained within the LCDM cosmological model.
