Hello Everybody,

This is a infinity game and the interest of it is in the 'Infinity'.

Anybody knows the limit of this game?take"Add 1, then say a username"as an example.

(Because the spam filter don't let me send links,I should post the rules here.Sorry for the inconvenience.

So, if it is a multiple of 3, say bobbym.

If multiple of 5, say anonimnystefy.

If multiple of 7, say n872yt3r.

If multiple of 11, say Agnishom.

If a multiple of 13, say Nehushtan if you are a boy.

If a girl, say mathgogocart.

Example :

1

2

bobbym

4

anonimnystefy

6

n872yt3r

8

9

10

Agnishom

12

Nehushtan)

So,How can I calculate the final limit(means that everybody need to speak a username)?

Let's see if I can understand what you want. Do you just want to use those 6 members names?

Then aren't you done at 12? We have used all 6 names up!

So what you are asking is what name would be for infinity?

No.I am talking that at somewhere near infinity (like that: )

You will have to be more precise than that. Infinity is not a number.

How about if we redo the rules. Start at 2, the first prime number. Choose a username for the #2.

The next poster will use the next counting number and if the number is a prime number then they

choose a username for it, but if the number is a composite number like 4 or 6, then they post all the

prime names that multiply to get that number 4 or 6, e.g. Does that sound fun??

Hi John;

Two different things. The OP wanted a definite answer, which is not possible to provide.

I have the result, but I do not yet know how to get it.
