3 | 1562533*2^6250134-1, but what for 1562533*2^6250134+1 ?

At first sight, this Cullen candidate has no small divisor...

Mr Karsten Haesslich, I hope you made a typo while posting this result

to Chris Caldwell !

something like: woodall(3125066). This would fit in with PrimeGrid's

current testing window,

Paul - If I submit the posted candidate to LLR, I get immediatly that :

1562533*2^6250134-1 has a small factor : 3 !!

So, if this number has really been tested using LLR (and not a smaller

one...), a false positive seems to be excluded...

I am now almost convinced there are hoaxes...

Sorry for him, and for me!
