Transfinite set is the implementation of a mathematical set. Normally, sets in software implementation are finite, but in mathematics they are often infinite. Since most of the behavior of wither type of set can be defined by the same operations protocols, we list them here. <br/>In Implementations, infinite sets (instances of TransfiniteSet, but not of set) are most often defined by the Boolean operation "includes" which test for the inclusion of a particular "T."<br/>
