One of the equations is blender (default) for the enneper surface.
The other is from Wikipedia:
I thought the formula would be what I’m looking for. I just took the default enneper formula and divided it by 3:
(u/3-u3/3 + u*v2)/3
(u2 - v2)/3
(v -v3/3 + v*u2)/3
(The resultant image):
(Looks like the default image only smaller. So, didn’t work)
The enneper image is a PovRay image from this page:
There’s a wealth of information in this PDF from this page:

(PDF here as well)

as I mentioned, math is not by strong suit, so, lots of math data, some which might prove useful using Sverchok Extras (another angle for this)
but, none of it I make heads or tails of in terms of my goal of the moment, a 3 sided Enneper surface.

Hope this helps, if I understand what you’re asking.
If not, let me know.
