This is the object that I am trying to find the volume of.

enter image description here

This can be treated as a "26 point star". What I need is an equation to describe it. If anyone has that surface in spherical coordinates R(Phi,Theta) that would be awesome. If not, the X,Y,Z solution can also be worked with.

This is a follow-up to work I was doing here:

What is the equation describing a three dimensional, 14 point Star?
