Question

Is ∞ an abstract term or a real number? And are there any numbers larger than ∞?

Answer 1

∞ is a concept describing something without any bound and larger than any natural number.

Answer 2

a number is defined as an arimethical value, expressed by word or symbol. by definition infinity is NOT a "number" as it holds no "actual" value.

infinity can not be represented so it is above digits. infinity squared would be uncountable thus infinity, therefore, there is no number higher than infinity.
