👉 The term "subassociative" refers to a binary operation that is not associative in nature. Specifically, if a binary operation \(a \circ b\) on a set of objects \(A\) (where the elements are also sets) has an identity element \(e\) and inverses \(f\) for all elements \(a \in A\), then it is said to be subassociative. In other words, if \(a \circ b = c\) holds for some \(a \
