When I read a paper (Conjecture 2.5 of paper link), I found a notation which is confusing,
$O(\log n~\text{factors})$.
I have no idea about the operation "factors"? What does it mean? Does it mean factorials? Many thanks!

You are expected to read it as $\big[O(\log n)\big]$ factors. The number in question has that many factors within a constant multiplier.
