Webiterated successorship. However, not every ordinality is of the form o′ + 1, e.g.! is clearly not: it lacks a maximal element. (On the other hand, it is obtained from all the finite ordinalities in a way that we will come back to shortly.) We will say that an ordinality o is a successor ordinality if it is of the form o′ + 1 for some WebIn mathematics, the cardinality of a set is a measure of the number of elements of the set. For example, the set = {,,} contains 3 elements, and therefore has a cardinality of 3. Beginning in the late 19th century, this concept was generalized to infinite sets, which allows one to distinguish between different types of infinity, and to perform arithmetic on them.

WebDefinition. Any finite natural number can be used in at least two ways: as an ordinal and as a cardinal. Cardinal numbers specify the size of sets (e.g., a bag of five marbles), whereas ordinal numbers specify the order of a member within an ordered set (e.g., "the third man from the left" or "the twenty-seventh day of January").
