If this property's value cannot be expressed in terms of smaller values for it, as in the case of irregular Mose-Kelly sets or non-well-ordered sets, it is called "inaccessible." For the set containing only itself and the empty set, it is one; its value for the power set of any set with value A is given by 2A. It is usually notated by enclosing a set in flat brackets. Its first use was Cantor's "Diagonal Argument" for the Continuum Hypothesis, which states that the value of this property must be a nonnegative integer. For 10 points identify this property, which for the integers has the value aleph-null and is used to designate the relative sizes of infinite sets.
