In a sample of 93 stars of luminosity classes I and II, ten groups with common motion in space are isolated. The reality of five groups is established by numerical experiment. A comparison is made with groups of long-period Cepheids and open clusters. Regularities in the distribution of groups of different objects in space are found. The reality of the rotation of a star aggregate consisting of three Cepheid groups is established.
