Is there any math symbol \predeq in Latex? If yes, how to use it?

share|improve this question
How is \predeq supposed to look like? Please post a picture of the symbol and have a look at “How to look up a symbol?” for ideas how you can easily find a particular symbol. – Henri Menke Mar 10 '14 at 7:10
It is written here. bitbucket.org/tgregoire/latexifier/commits/…. But I can not compile. – user12290 Mar 10 '14 at 7:24
Well, you should be able to show us how it should look like. You can draw a picture if you like. You can easily upload image files here. – Dr. Manuel Kuehner Mar 10 '14 at 7:27
My feeling is that \pred and \predeq are typos for \prec and \preceq – egreg Mar 10 '14 at 7:55
Thanks for your help. – user12290 Mar 10 '14 at 8:14

The line in that linked Unicode map shows:

-precedesequal 8826 T \predeq

See PrecedesEqual on wolfram.com:

PrecedesEqual symbol

You can find that symbol in the Comprehensive Symbol List, for example in the binary relations table as \preceq:

Here's the fishing rod, instead of the fish itself:Detexify! Just tried it and it returned \preceq as the first result. It is probably a good chance to mention that a mobile version (android and iOS) is available as well.
