👉 Semiperiphery is a term used in mathematics and computer science to describe the part of a circle that lies outside of the two concentric circles surrounding it. It is often referred to as the outermost or outer boundary of the circle, and it marks the edge where the diameter (the longest chord) of the circle intersects with itself. The semiperiphery can be defined in terms of arc length, which is a measure of how far an entire circular path traces out from the center.
