This is known as the "meter" in music, i.e. 2/4, 3/4, 4/4, etc. "Measures" aka "bars" delineate each pattern of beats.
Compounds are made when atoms of 2 different elements are combined in regular forms.Repeating patterns of either atoms (one element) or molecules (2 or more elements), or perhaps ionic bonded atoms (2 or more elements, ionic bonds) are found in solids.The most regular patterns are found in crystals which is a type of solid.

The objects that repeat in a predictable way are called "patterns". These patterns can be identified based on a specific sequence or arrangement of elements that recur regularly.
They simply call them recurring actors
The study of patterns in nature without explaining them is called descriptive science. It involves identifying, documenting, and categorizing recurring patterns or structures in natural phenomena without delving into the underlying causes or mechanisms. This approach is commonly used in fields such as biology, ecology, and geology to aid in classification and observation.
Terminating. Non-terminating but recurring. Non-terminating and non-recurring.
The question apparently needs to be more specific for me to understand it. A pattern by itself is a theme of recurring events or objects that are predictable (usually regularly repeated, hence my confusion). Each event or set of objects that repeat are called cells. Pattern matching is the act of checking for patterns, pattern formation is the investigation of how patterns emerge. Some types of patterns are fractals, tessalations, crystal structures, harmonic motion, sequences (for example Fibonacci numbers). Names for patterns have specific applications, such as visual patterns, audible patterns, numeric patterns, etc. Perhaps some starting points that might help are in the links below. ostinato
The law of a politically organized body is called a constitution.
That rhyming pattern is known as a "quatrains," where the lines follow an AABA rhyme scheme. Each letter represents a different rhyme sound.
