👉 In mathematics, a "gemination" is a specific type of permutation problem where each element in the set can be repeated any number of times. This means that you have to find all possible permutations of the elements and then order them so that they are in some particular order. For example, if you have a set of 4 numbers {1,2,3,4}, the possible geminations would be: 1,2,3,4 1,3,2,4
