Finally, I'm not aware of a commonly used term for the "must be equal" symbol (exclamation mark set over equality symbol). In addition, when I try using it within \begin {equation}, I have to use \mbox {=} to display anything at all (I still just get the one line). The triple bar symbol ≡ (U+2261, LaTeX \equiv) is often used to indicate an identity, a definition (which can also be represented by U+225D โ EQUAL TO BY DEFINITION or U+2254 โ COLON EQUALS), or a congruence relation in modular arithmetic.
