We propose detailed scheme that is
describing the morphology of linear substructures in
galaxy clusters. Our base morphological scheme di-
vides galaxy clusters using numerical criteria according
the parameters: concentration to the cluster center, the
presence of linear substructure, orientation of images
of galaxies, the role of brightest cluster members, the
shape of galaxies.
Our analysis of 2D distribution of galaxies based on
study more than 500 galaxy clusters. We show the
linear substructures are regular peculiarity in galaxy
clusters. Our approach allows to divide filamentary
and edge-on wall substructures and to select galaxy
clusters with possible peculiarities in hot gas and/or
DM distribution.
