👉 In mathematics, a subinvolution is an operation on a set that reverses each element of the set before applying it. This means that if we have a set A with elements {a1, a2, ..., an}, then a subinvolution on A can be defined as follows: for any two distinct elements x and y in A, the result of applying the subinvolution to (x) and (y) is x and y, respectively. The term "subinvolution
