What is the biggest number before infinity?

Answer 1

Infinity is not a number, and there is no "biggest number" since numbers increase in size forever.

The biggest number with an English name is called "Graham's number" and it is too large to write down, even in scientific notation.

Answer 2

Infinity minus 1 = infinite, so there is no infinity. That is because infinite definition is never ending.

Answer 3

Dealing with whole numbers, it would be infinity minus one - if that is even possible since the term represents a never ending concept.

Answer 4

There is no such number. Whatever number you choose, you can always add one more, WITHOUT reaching infinity.
