How to write this symbol in Mathjax?
Another symbol(maybe better one) for Natural numbers set

I'm already familiar with \Bbb{N} code but prefer the above symbol!
Is it possible to depict it using Mathjax?

    $\begingroup$ Oh, the things we did before TeX: $\mathbb{N,R,Z}$ were not too hard. How did you do $\mathbb Q$? $\endgroup$

  • $\begingroup$ What I saw back then was Q backspace I, so that the I comes out in the middle of the Q. Like this $\;\mathrm{Q\!\!\!I}$ ... Not much like $\mathbb Q$. $\endgroup$

Typing $\mathrm{I}\!\mathrm{N}$ yields $\mathrm{I}\!\mathrm{N}$.

    $\begingroup$ I'd recommend against using this to typeset a "bold" N. This could lead to varied confusion. $\endgroup$
