Abstract
A new method to characterize the strength of magnetic frustration is proposed by calculating the minimum dimensionality of the absolute ground state of the classical nearest-neighbor antiferromagnetic $n$-vector model with arbitrary $n$. Platonic solids in three and four dimensions and Archimedean solids have lowest-energy configurations in a number of spin dimensions equal to their real-space dimensionality. Fullerene molecules and geodesic icosahedra can produce ground states in as many as five spin dimensions. Frustration is also characterized by the maximum value of the ground-state energy when the exchange interactions are allowed to vary.

Strengths
It is a comprehensive work on magnetic frustration for various theoretical model spin systems.
Weaknesses
This work extends the existing knowledge about magnetic frustration in model spin systems, but I don't see any significant impact for that on the physics of these systems. Furthermore, I am missing a connection to existing systems and/or experimental studies.
Report
The manuscript does not meet the acceptance criteria of the journal. I recommend publishing it in SciPost Physics Core.
