Why is the conjugate alteration of the Mandelbrot set (the tricorn) also known as the "Mandelbar" set?

Question

I am currently working with a shader rendering that deals with higher powers of the Mandelbrot set, . I understand that the conjugate of the first parameter of this set,, also known as the tricorn, is called the mandelbar set.

This is almost certainly some kind of a play on words; but while I've encountered multiple sources using this terminology, I'm not personally getting it. Can anyone explain why the tricorn is also referred to as this? Where is the -bar suffix coming from?

Thanks.

Look up "z bar math" . The symbol $\overline z$ is often pronounced "z bar"
