From those pages, I learned about the
mathabx package and its
\precneq symbol. However I noticed that it uses a modified version of the
\prec symbol. It isn't a replica of the standard
\prec symbol. Instead it uses a modified version of
I've been trying to research how to construct a math symbol that's a modification of either
\preceq but to no avail. Does anyone have solution/advice?
The solution in Element of or Equal To Symbol is extremely nice (I prefer the "roundcap bar" version); More generally is there a general procedure for making such "or not equal to" symbols from already defined binary operators?
