Magic star

Special arrangement of numbers on a star

An n-pointed magic star is a star polygon with Schläfli symbol {n/2} in which numbers are placed at each of the n vertices and n intersections, such that the four numbers on each line sum to the same magic constant. A normal magic star contains the integers from 1 to 2n with no numbers repeated. The magic constant of an n-pointed normal magic star is M = 4n + 2.
