That's a power series for sine, so it's a factorial

Or it's just some esoteric notation for factorials, which would make much more sense in this case, since L wouldn't actually fit there.

No I'm conviced >>12999259 was right, the usual notation is for a factorial is n! but this is simply a taylor expansion of sin(x) around 0

Yes.

So >>12999330 is simply:
$\sin\theta=\theta-\frac{\theta^3}{3!}+\frac{\theta^5}{5!}-\ldots$
