### Re: The biggest number?

hi

Can you prove this is bigger than the number from post #23 ?

### Re: The biggest number?

Yup.Your number has 27 digits (look at wolfram's output).Mine clearly has 51.

Fair enough.  I bow to your use of Wolfram to actually calculate the number.

### Re: The biggest number?

I didn't calculate the whole number. It showed it in tge form a.bcdefg... x 10^26. There were a few more digits in the decimal,but tge number still stays 27 digits long. What is your number?

### Re: The biggest number?

So I'll have

This number needs no computation as such but if you wanted to write it down, then, at one digit per second, you could do it in half a year.

You haven't set a limit on how much paper I am allowed.

### Re: The biggest number?

Computers can carry out those computations in quite a reasonable time,so I think it would be accepted. You can even get a closed form of that by hand and it becomes quite obvious what the number is.

My number is (((3!)!)!)!

### Re: The biggest number?

There is no such thing biggest number but bigger number because of the fact 1/x is too big when x=0. If there is such thing biggest number, it could always be 1 because the infinite universe was confined in a single unit when t=0s during the big bang:)

### Re: The biggest number?

Yes,that is right. But the point is finding a bigger number than somwbody else in the quest of searching for the biggest number,which of course doesn't exist.

Apparently it is 10^10^10^2 away from ganesh's number.

Hi anonimnystefy,

The smallest number apart from 0 and 1 which is a perfect square, cube, fourth, fifth, ...., and one thousandth power is roughly

.

The number which is the smallest number apart from 0 and 1 which is a perfect square, cube, fourth, fifth, .... and googolplexth power which would be much much greater!

### Re: The biggest number?

But I want to know that you can compute these suggestions.

Your number must also be computable in a reasonable amount of time (e.g. Within half a year ).

I think it will be better if ganesh answred that question,cause mine is just a one added to the 10^10^2 place.

### Re: The biggest number?

I estimate the number by rough calculation. The answer would be roughly lesser than

.
I am not sure with the powers. The only I may say with some degree of accuracy is the upper limit seems relatively certain.
