How to write the set of quaternion numbers in Latex !

In old books, classic mathematical number sets are marked in bold as follows

`$\mathbf{H}$ is the set of quaternion numbers.`

So we use the **\ mathbf** command. Which give:

$\mathbf{H}$ is the set of quaternion numbers.

You will have noticed that in recent books, we use a font that is based on double bars, this notation is actually derived from the writing of classic sets on the blackboard: indeed, on the blackboard we do not fill these sets, or it would take a ton of chalk !!! In Latex, we use the **amsfonts** package

In the preamble we have:

`\usepackage{amsfonts}`

and **\mathbb** command

`$\mathbb{H}$ is the set of quaternion numbers.`

$\mathbb{H}$ is the set of quaternion numbers.
