Abstract
The antiferromagnetic Heisenberg model on the fullerene C$_{60}$ in a magnetic field has $4s$ ground-state magnetization discontinuities as a function of the spin quantum number $s$ that disappear at the classical limit. The molecule can be seen as the fullerene C$_{20}$ with interpentagonal interactions that can be tuned to generate the discontinuities. The results show how spatial symmetry dictates the magnetic response of the $I_h$ fullerene molecules.

Report
My general recommendation is still the publication in Scipost physics because of the insights into the magnetization plateaus of a large molecule with a smart approach (which can also be used for other molecules).
However, I still have concerns about the presentation. The additional figures help to clear the situation but due to the high amount of tables the reading flow is limited. In my opinion, it is worth to rethink if some of these data can be placed outside of the paper.
Requested changes
1) Fix typo in caption of Figure 11: remove parenthesis from red and green.
2) The graphical representation of C20 and C60 seems very large and the three-dimensionality is hard to sea. This should be improved or alternatively some projection to the 2D plane (e.g. Schlegel projection) should be used.

Report
The journal's criteria are met because the complexity of the problem (C60 is roughly equivalent to a finite, but large periodic 2D system) is solved using insights rather than hard numerics. The ideas presented in the paper can be expanded to cases of even larger molecules or fermionic systems, where state-of-the-art numerical methods fail.
