- How to type NOT \delta and NOT \ll 3 answers
I am using letter R for notation for my relation. I have to use the
wRw notation. My problem is that I can't write
\not R as I would like to. So I would like to write that, let's say a,b are not in relation with each other and type
a\not R b.
It just doesn't look good.
