# How do I get this Mathematical Symbol in Latex?

I am doing a project report and there is a certain kind of relation that I want to express between two quantities A and B. The relation is something like "A is neither greater than or less than B" (These two quantities are not numbers, they are kind of valuation profiles that I need in my project). Anyways, I wanted to create a symbol to denote this relationship. Something like the image attached. Can anyone please help in creating it. (Or let me know if such a symbol already exists). Thank You..

• Welcome to TeX.SE! Search for "The Comprehensive LaTeX Symbol List". It contain all known symbols. Maybe it already exist. – Zarko Jul 18 '16 at 0:37
• It could make sense. For instance, a matrix could be neither positive definite nor negative definite, and you might want a symbol for that property. Indeed, it's close to the concept of indefinite matrix. – JPi Jul 18 '16 at 1:00
• As a tangential remark: in order theory there are established notions of incomparability. Wikipedia gives one set of notations that is somewhat frequently in use. – Willie Wong Jul 18 '16 at 2:15
