Pretzel Surface
The Pretzel surface is an algebraic surface.

# Basic Description

The Pretzel surface is an algebraic surface.

# A More Mathematical Explanation

The equation for the pretzel surface is given by:

$f(x,y,z) = (((x-1)^2 + y^2 - aa^2) * ((x+1)^2 + y^2 - aa^2))^2 + z^2$

The equation for the pretzel surface is given by: $f(x,y,z) = (((x-1)^2 + y^2 - aa^2) * ((x+1)^2 + y^2 - aa^2))^2 + z^2$
