The regularity in the distribution of young stellar groups along the spiralarms of galaxies, first discovered by Bruce and Debra Elmegreen in 1983, wasconsidered a rather rare phenomenon. However, recent studies of the spatialregularities in the distribution of the young stellar populations along thearms of the spiral galaxies NGC 628, NGC 895, NGC 4321, NGC 5474, NGC 6946, aswell as along the rings of the spiral galaxy NGC 6217 and the lenticular galaxyNGC 4324, have revealed that this spatial (quasi) regularity and/or thepresence of regular chains of star-forming regions is a fairly commonphenomenon. Across all galaxies, the characteristic regularity scale is 350-500pc or a multiple thereof. It should be noted that theoretical models predict aninstability scale of a stellar-gas disk on the order of a few kpc, which isseveral times larger than what has been observed. The paper is partly based onthe report presented at the Modern Stellar Astronomy 2022 Conference held atthe Caucasian Mountain Observatory of the Sternberg Astronomical Institute,Moscow State University, on November 8-10, 2022.
