“…From left to right: map, distribution of density of galaxies in the bands, corresponded to L5 subtype and distribution of cosines of acute angles between the direction of L5-line and all galaxies inside the central (main) band. Emelyanov, 2017, 178 rich intermediate (Panko et al, in preparation) and 28 rich concentrated galaxy clusters , as well as 112 ones placed in richest regions of southern sky (Panko et al, in preparation). Our experience allows us to simplify and to specify the detailed classification of linear substructures as L5...L11.…”

We propose detailed scheme that is describing the morphology of linear substructures in galaxy clusters. Our base morphological scheme divides 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.

“…The improved types correspond to concentration to the center (C compact, I intermediate, and O open), preferential line presence (L line, F at, and no symbol if no indication of atness is present) and the role of bright cluster members, namely cD or BG if the bright cluster's members (BCMs) role is signicant. Other peculiarities are noted as P. The special kinds of regular peculiarities, such as X-type (crossed bands) and Y-type (divaricate laments) with corresponding positions and orientations of the BCMs; curved strips and short chains were detected in open rich clusters (Panko & Emelyanov, 2017;Panko et al, 2018).…”

The results of the detailed analysis of the 2D distribution of galaxies in 28 rich galaxy clusters with signicant concentration to the cluster center are present. The analysis was executed in these directions: the detection of regular substructures and peculiarities in the galaxy distribution. The role of brightest cluster members was taken into account too. The input data were selected from The Catalogue of Galaxy Clusters and Groups and list of galaxies of Muenster Red Sky Survey. Concentrated galaxy clusters are evolved, virialized structures. Substructures in this type of clusters must be feeble marked. Nevertheless we detected signicant part of concentrated galaxy clusters having dierent kinds of peculiarities, namely crossing and divaricating laments or X and Y-type peculiarities, as well as curved strips and short dense chains. 2 clusters having extremely density of galaxies were attributed as superconcentrated/compact type.
