## $\Omega$ Notation: Also known as
Note that in the Greek alphabet, $\omega$ is the minuscule counterpart of the capital letter $\Omega$.
Some sources, therefore, write $\omega$ notation as little-$\omega$ notation, despite the fact that $\omega$'s "little"-ness is intrinsic.
$\mathsf{Pr} \infty \mathsf{fWiki}$ may sometimes adopt this convention if clarity is improved.
