Description bobharvey 2004-07-14 10:52:07 UTC 
I can say "equiv" with the best of them. But I want a diagonal slash through it 
to denote non-congruent.  The closest I got was:
http://www.oooforum.org/forum/viewtopic.php?p=36104&highlight=#36104

I quite like the "nequiv" idea - after all we have  nsubseteq  and notin 

Another possibility would be a sort of re-position facility to let you put 
anything on top of anything else: something like A back B .  

Or you could expand the attribute idea: like   grave, vec, or phantom  you could 
have slashthrough (slashleft, slashright, slashvert ?).  That would allow us to 
put a slash through a whole equation, if we wanted to.  For some reason.  That I 
won't have thought of till next friday.  It could go with the box in issue 31176

kind of non-congruent or non-equivalent is not available in OOO's symbol set.
Comment 2 rgb 2004-07-14 11:39:04 UTC 
I think the idea of superpose characters could be a great improvement, not only
for the non equivalent. I am thinking as a teacher: it would be great to put a
line across a common error (if it could be on other colour, best)
Comment 3 bobharvey 2006-07-01 10:31:07 UTC 
I still think this is a good idea, 2 years on.
The Math module has not advanced, and if the uwer forums are to be believed is 
rather problematic.
