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..
