Transversality symbol (upside down Phi)

Does anyone know how to produce the symbol for transversality ? It can
be represented as an unpside down Psi. I have been using a \cap symbol
with a vertical line through it but this does not seem to work well
since, its appearance depends on its location in each equation and
therefore looks different almosr each time it I use it.

I had a similar problem constructing an upside-down ampersand,
until I saw someone else solve it using the sprite.sty option
to construct one explicitly. The example I used is available at
ftp://boole.stanford.edu/pub/TEX/ql.tex.gz
You'll have to work a little to ``deconstruct'' it and figure out
what's necessary and sufficient for the sprite itself. But maybe
someone else can suggest a simpler solution. Hope this helps,

I would not recommend this solution, because it involves an explicit
bitmap and therefore produces device-dependent output (worse than
dvips as you encode the bitmat explicitly in the .sty file).
Moreover, it contains low-level surgery in LaTeX 2.09, which
is likely to break in unexpected situations, now or sometime
in the future.

Why don't you simply use the graphics or the graphix package
which has a \rotatebox command? Read the graphics docs!

I think you are describing the \pichfork symbol which is provided in
amssymb.sty.

It is in the AMS symbol set (\usepackage{amssymb} in LaTeX)
and called \pitchfork
