Prime Countdown

Please start at the largest prime less than $\infty$

There are no primes greater than 1.

$\infty$ - 1 and $\infty$ - 3 are twins.

akruppa · 2007-09-20, 11:56

So are $\infty$ - 1 and $\infty$ + 1.

Since $\infty$ = $\infty$ ²,

$\infty$ - 1 = $\infty$ ² - 1

which is factorable, hence composite.

There is no such thing.

Thread locked; will unlock if thread starter is able to make problem well-posed, and convince me this is something other than an attempt to start an interminable spam-thread.

I think it's a humorous follow-up to the prime count-up thread. Judging by the comments, everyone understood it as not to be taken seriously.
