# Less AND greater than symbol [duplicate]

I need to know, if it's possible, how I can write a unique "less AND greater than" symbol in LaTeX: for example X >< 5.

 Isn't it <> instead of ><? – poitroae Feb 11 at 10:27 Sorry, my mistake, I'll write on tex.stack the next time... However, I was wrong to write: I wanted to say <>... – Daniele Feb 11 at 10:33 @Daniele Please do not cross post to TeX - LaTeX.

That's not possible (unless you write the greater than symbol followed by the less than symbol).

You can find a comprehensive list of LaTeX symbols here.

EDIT:

For something that looks like an horizontal X, check out \times and \openJoin in the document.

For one over the other, check \lessgtr, from comments I think that's what you're looking for :

mmm are you sure? Because I red something like that in some books in the past... However thanks a lot for the link... It's wonderful! – Daniele Feb 11 at 10:34
I found one that looks like a > on top of a < but that's all... You don't like how >< looks like? Are you looking for something more like an horizontal X? – alestanis Feb 11 at 10:47
No no... I'm looking for something like a > on top of a <... sorry, but I think that I explained that very bad... How can I do that? – Daniele Feb 11 at 10:55
@Daniele Check my edit, is that it? – alestanis Feb 11 at 10:57
The needed package is amssymb – egreg Feb 11 at 12:58
