WebJan 6, 2009 · It turns out many sets are equivalent to the natural numbers; we call these sets denumerable. For example, the set of Turing Machines is denumerable because there are infinitely many machines and they can each be fully described by a distinct natural number. The integers are yet another example: WebA 'countable' infinity is one where you can give each item in the set an integer and 'count' them (even though there are an infinite number of them) An 'uncountable' infinity defies this. You cannot assign an integer to each item in the set because you will miss items. silent night dress
