What does this symbol mean $$\bar{\in}$$? I know what $$\in$$ is but I never saw it with a line on top.

edit. I figured it out I think It was used because they can't print $$\notin$$

Try typing the context or the formula you found that... the stand-alone symbol could mean anything!

I think you will find this in older manuscripts, before $\notin$ became common.
