How to write this symbol in Mathjax?

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

• Oh, the things we did before TeX: $\mathbb{N,R,Z}$ were not too hard. How did you do $\mathbb Q$? – GEdgar Jun 17 '16 at 12:43

• 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 $\mathbb Q$. – GEdgar Jun 19 '16 at 12:16

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