This template is used to include the triple closed integral, usually in a mathematical formula. It overcomes a limitation of the TeX rendering which cannot display this symbol without clumsy workarounds.
All parameters are optional.

The \oiiint command is not part of AMS-LaTeX, and thus not part of the math support that MediaWiki provides. It is available as a unicode character U+2230 ∰ but font support for this character can be lacking. For this reason, the template provides an image variant of the character.
