Ordered and unordered pairs
WebThe ordered pair ( a, a), as a set, is a set which can be written as { { a }, { a, a } } or as { { a }, { a } } or as { { a } }. There is no problem with this, because that set has the property that ( c, d) is equal to { { a } } if and only if c = d = a, which is exactly what we want.
