I hope the code below solves this problem.
Experiment with the Xnr and Znr values (integers) to see how these
works. (Also see attached image.)
I think that it's possible to construct a "ReplikateFunction" that
also can generate grids of isosurfaces with an even number of "parts"
along each side.
Btw.:
You have a nice scene with interesting functions and patterns !
