👉 A trivalency is a property of a mathematical object that does not require any additional information to be defined. It refers to the fact that every mathematical object has a unique, complete description without requiring any further details. For example, in abstract algebra, a group G can have many different structures depending on its elements (e.g., cyclic groups, permutation groups, etc.), but each of these structures will satisfy the axioms of group theory because they are uniquely determined by their structure and properties.
