I was making a fault tree and needed an And gate. Found it, no problem. My search also turned up something called a "Vertical P And" symbol in the Miscellaneous Flowchart Symbols template.
What the heck is a P And?

A dumb idea.
The "Vertical P And" shape is actually an OR gate and the "Vertical XOR" is actually an AND gate, so &&&& knows.
I suspect many of the shapes in some stencils are there just to make up the numbers and in real life are as useless as a chocolate teapot.
