xkcd 2861: X Value
(imgs.xkcd.com)
Alt text:
The value of n is still unknown, but new results constrain it to fall between 8 and 10^500, ruling out popular 'n=1' and 'n=2' theories.
Hmm you're right, honestly I just googled and saw the same exact number with a decimal point shifted, so I put two and two together
As for whether that number is actually a valid valuation, I've not got the information to say
