The complex mathematics for the Python script is based upon three papers by Paul J.F. Gandy, and Jacek Klinowski:

"Exact computation of the triply periodic G ('Gyroid') minimal surface," (& D & P), available at:
https://dokumen.tips/download/link/exact-computation-of-the-triply-periodic-g-gyroid-minimal-surface

https://www.researchgate.net/publication/234138905_Exact_computation_of_the_triply_periodic_D_'diamond'_minimal_surface

https://www.researchgate.net/publication/223147236_Exact_computation_of_the_triply_periodic_Schwarz_P_minimal_surface

(The papers are very similar, and complement each other, but do have some inconsistency errors/ typo's, and some elements that are not entirely understood.)

Symmetry operations will be done in MoI.
Next, the input domains for the D_diamond and Schwarz_P surface will be processed.

Low density .3dm of the patch attached. Just perform MoI Network on it...

It has been a few months since I studied the symmetry (mirror) planes, and rotational axi...must review.
