17: sometimes there are multiple sizes, according to the spec (https://html.spec.whatwg.org/multipage/links.html#rel-icon)

18: sometimes favicons are not square

19: sometimes favicons have transparent pixels (GIF) or an alpha channel (PNG)

Good ones! I forgot about the transparent pixels.

May I add those with credit to you?

ICO files can have an alpha channel or a bit mask.
