# Trying to identify mathematical symbol

I encountered this symbol in an old Adobe mathematical character set, and I'm trying to identify it. I can't find it on Wikipedia's list of mathematical symbols, and it's difficult to describe it for the purposes of a Google search.

Here is an image:

And ... What now? What's your question? –  Gigili Dec 28 '11 at 20:34
I've been trying to draw it at detexify.kirelabs.org/classify.html but with no luck so far. –  Qiaochu Yuan Dec 28 '11 at 20:35
@Gigili, my question is: what does this symbol mean? –  Channel72 Dec 28 '11 at 20:36
This might help: detexify.kirelabs.org/classify.html –  Erno Nemecsek Dec 28 '11 at 20:37
It would possibly be easier if you could provide some context that you have seen this symbol in. –  Henning Makholm Dec 28 '11 at 20:38

This looks like U+03D0 GREEK BETA SYMBOL. See the unicode chart containing it.

Apparently it's just a typographical variant of $\beta$ that someone may have used for some particular purpose, like some distinguish $\phi/\varphi$, $\epsilon/\varepsilon$, $\theta/\vartheta$.

Good eye, @Henning :-) –  robjohn Dec 28 '11 at 20:59
According to this PDF, the unicode for this character is 0x3D0, which is The Greek Beta Symbol (an alternate).
Here it is in $\LaTeX$: $\Huge\unicode{x3d0}$.
@Srivatsan: $\unicode{x0392}$, $\unicode{x03B2}$, and $\unicode{x03D0}$? –  robjohn Dec 30 '11 at 14:25
