Test post with latex code in it.

This is latex math code:

\{ \omega^{\omega^{\omega^{\omega^{...^{\epsilon_{0+1}}}}}} \}

 f_{\epsilon_0} (6) = f_{\omega^{\omega^{\omega^{\omega^{\omega}}}}}(3)

That is also a really big number on the fast growing hierarchy.

Up arrow notation

3\uparrow\uparrow\uparrow\uparrow3

This is an example of up arrow notation. Also called Knuth’s up arrow notation.

Latex seems to be first class in WordPress. It works very nicely across the platform. Results look accurate.
