I want to express an unordered m-tuple (or symmetric m-tuple) as < a_1,...,a_m >. So while writing I used greater and less than symbols ( >', <' )from the keyboard but that is causing some spacing problems. So I looked up the commands (on tug.ctan.org/info/symbols) for angular brackets and they are \lAngle, \rAngle etc. But these are not working because I am using ams symb. Could anybody tell me what are the appropriate packages to use? Thanks a lot!

    $\begingroup$ You are probably better off asking this question at TeX - LaTeX, but \langle and \rangle produce the correct symbols. You might need one of the AMS packages for this, but I don't think so. $\endgroup$

Seems like it's a capitalization issue. No special package is required for \langle $\langle$ and \rangle $\rangle$.
