We analyzed 377 ACO clusters to obtain shape of the structures. The covariance ellipse method was used to ellipticity determination. We discuss the shape of two samples: the first one contains all galaxies in the magnitude range m3, m3 + 3m and the second sample contains only 20 brightest galaxies. Statistical test shows the difference in the ellipticity distribution in those two samples. The counts of galaxies located in 12 sectors of the circles 30? for two samples were performed. We found that the location of 20 brightest galaxies in the cluster is different that the distribution of all galaxies in the same structure. These results are not in contradiction with the naïve predictions coming from the Ambartsumian idea.
