The term “regular” is deployed with remarkable flexibility in literature, spanning contexts from the everyday and habitual to the systematic and institutional. It is used to describe organized phenomena such as scheduled military services and standard practices ([1], [2], [3]), as well as to denote patterned or rhythmic biological functions like breathing or heartbeat ([4], [5]). The adjective conveys notions of conformity, reliability, and uniformity in contexts as diverse as employment conditions ([6]), disease patterns ([7]), educational routines ([8], [9]), and even the measured order in mechanical or artistic creations ([10], [11]). In this way, “regular” not only signifies what is normal or customary, but also informs our understanding of structure and discipline in various realms of human activity and natural phenomena ([12], [13]).
