uncountable set
英[ʌnˈkaʊntəbəl set]美[ʌnˈkaʊntəbəl sɛt]
In mathematics, an uncountable set is an infinite set that contains too many elements to be countable. The uncountability of a set is closely related to its cardinal number: a set is uncountable if its cardinal number is larger than that of the set of all natural numbers.
