 Magic circle (mathematics)

In mathematics, particularly in the area of group theory, the term "magic circle" may refer to a specific concept or structure used in the study of groups, particularly in the context of group actions and geometry. However, it's not a widely recognized term like "magic square." One common usage of the term might be in relation to **magic squares** where numbers are arranged in a square grid such that the sums of each row, column, and sometimes diagonals equal the same constant.
