👉 In mathematics, a supersuborder is a subset of a given order relation that contains more than one element. It is defined by stating that every element in the original ordered set (the superset) has an immediate predecessor or successor in the supersubset. For example, if we have two sets A and B, then the supersubset of A is B with the following elements: A = {1, 2, 3, 4, 5, ...} B
