I do not know about what question you asked, but there is one type of question which I think people should never ask on the internet. Those are tye questions which can be answered faster than writing down the question.

You can google "list math symbols" to get: https://en.m.wikipedia.org/wiki/List_of_mathematical_symbols...

I don't know what math symbol you were looking for, but I suspect it is in there and most of your questions could have been answered by a few minutes of looking at that list.
