# Thread: Curly braces between MATH tags cause unknown error.

1. ## Curly braces between MATH tags cause unknown error.

Hi:
I am sending the whole text bellow:

Hi:
In the book The Theory of Finite Groups: An Introduction, by Hans Kurzweil and Bernd Stellmacher, New York, 2004, in section 1.6, Products of Groups, there is Exercise 3:

Let $\displaystyle G$ be finite. Suppose that every maximal subgroup of $\displaystyle G$ is simple and normal in $\displaystyle G$. Then $\displaystyle G$ is an Abelian group and $\displaystyle \{ \}$, where $\displaystyle p, q$ are primes.

END OF TEXT

'and [LaTeX ERROR: Unknown error] , ' should be replaced by 'and MATH_TAG \{ \} /MATH_TAG, '

Would you be so nice to tell me what to do?

EDIT
More simple than that: the following text:

]MATH[ \{ ]MATH[

causes LaTeX ERROR: Unknown error. I wrote inverted square brackets on purpose, only here.

We're using $$*insert latex here*$$ as a "temporary" fix.

Note I've edited the quoted post to use tex tags

When I use $$tags I get an error: [tex]\Delta P = \rho g \Delta h$$ ----> $\displaystyle \Delta P = \rho g \Delta h$

$$\Delta P = \rho g \Delta h$$ ---> $\displaystyle \Delta P = \rho g \Delta h$

edit: math tags are working again (Even in part)? That's news to me. But using tex tags still seems to solve your problem

Thanks a lot. In the Latex Help forum, I've just seen someone posted a forum-wide announcement, regarding this matter. Do you know where it is located?

And, if you don't mind: what's the latex string for 'normal in', as in H normal in G?

This thread is now in the LaTeX area of MHF, look about six threads down and you will find what you want.
