Higher-dimensional directed tori: nested return maps, odometer models, and parity behavior

Investigate whether higher-dimensional directed tori Dd(m)=Cay((Z_m)^d,{e1,...,ed}) for d≥4 admit nested return-map analyses that yield finite-defect odometer models comparable to those used for D3(m), and determine whether odd and even ambient dimensions exhibit genuinely different parity behavior in such constructions.

Background

Beyond the 3-dimensional case, the author envisions a broader program where low-layer defects are organized by successive return sections until a finite-defect odometer emerges.

This raises two related questions: whether such nested-return/odometer models extend to composite higher-dimensional products of directed cycles, and whether there are systematic parity distinctions between odd and even ambient dimensions.

References

Several structural questions remain. More broadly, it is natural to ask whether composite higher-dimensional cases admit comparable nested return maps and finite-defect odometer models. It would be especially interesting to understand whether higher-dimensional directed tori admit equally clean nested-return descriptions and whether odd and even ambient dimensions exhibit genuinely different parity behavior.
