# TeX beth symbol missing [duplicate]

Possible Duplicate:
Tex \implies symbol does not work

In this post I cannot get the TeX symbol $\beth$ to work. I checked and the symbol does work on MathOverflow, so it may just be a configuration issue.

MathJax supports the beth symbol upon enabling the AMSsymbols extension. This is something the StackExchange admins would have to fix. People have been running into this problem before [1, 2].
May I recommend that you change your question into a general request for enabling AMSsymbols in MathJax?
