This question is related to Element of or Equal To Symbol and Creating a \precneq symbol.
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 \prec
.
I've been trying to research how to construct a math symbol that's a modification of either \prec
or \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?

Here's a solution that builds the underbar with the help of picture mode.
