Yet another math symbol

Yet another math symbol

[Oliver Buerschaper]

Hi all,

I'm struggling to typeset the math symbol "identity" ... it looks  
like a "1" but with double vertical lines. Hints very welcome ;-)

What if we put together an extensive table of all math symbols  
available in ConTeXt at some point?

$\parallel$

HTH

I use a "TeX reference Card" page I found on the web but I really agree 
with you

Best

No, it's not this one, but really the figure "1" only featuring a  
double vertical stroke ... like {\Bbb R}.

no answers, but can you see it with \showmathcharacters ?

Wicked! That already comes quite close to a nice lookup table ...

However, I can't see my little identity symbol :-(

Any other ideas? Is it perhaps contained in \Bbb in some character slot?

Do you mean something like 1 at the end of eq (23) page 4 (3231) at 
http://www.eecs.umich.edu/~adityam/publications/conferences/cdc2006.pdf

That symbol is from dsfont package in LaTeX. Fonts are not my forte, 
but maybe it can be used the same way as rsfs fonts.

Since I needed to use it in ConTeXt also, here is how to use it.

I reused the mb family since I do not expect anyone to use double 
stroke with blackboard bold.
