    • In our simulations, we use the criterion | mi | > mmin for nonzero eigenvalues, where mmin = 10-6 is the noise threshold for our eigenvalue calculations. Also, eigenvalues are considered to be equal if they differ by less than the noise threshold mmin.

    • We have also calculated the family length distribution using the eigenvalues of the connectivity matrix to determine the strains at which geometrical families begin and end, which is identical to the length distribution shown in Fig.. (See Appendix).

    • It is also possible that plotting J does not adequately distinguish one MS packing from another; however, we have verified that the sequence of eigenvalue lists and polarizations at the beginning of the second cycle match those at the beginning of the first.
