Quaternions
- $\Bbb H$
The set of quaternions.
The $\LaTeX$ code for \(\mathbb H\) is \mathbb H or \Bbb H.
Historical Note
The symbol $\Bbb H$ was selected to denote the set of quaternions in honour of William Rowan Hamilton.
Of course, $\Q$ could not be used, because it had already been adopted to stand for the set of rational numbers.
