👉 Wreathwise is a mathematical concept in topology and combinatorics. It refers to the number of ways one can arrange n objects into a geometric shape, where each object has exactly two neighbors (including itself). This concept was first introduced by the Swiss mathematician Henri Poincaré. The general formula for calculating the number of arrangements of n objects into a geometric shape is: n! / [k!(n-k)!] Where "!" denotes factorial, which refers to the product of
