Description: Find the permutation symmetry group such that the
        covariance matrix of the given data is approximately invariant
        under it. Discovering such a permutation decreases the number
        of observations needed to fit a Gaussian model, which is of
        great use when it is smaller than the number of variables. Even
        if that is not the case, the covariance matrix found with
        'gips' approximates the actual covariance with less statistical
        error. The methods implemented in this package are described in
        Graczyk et al. (2022) <doi:10.1214/22-AOS2174>. Documentation
        about 'gips' is provided via its website at
        <https://przechoj.github.io/gips/> and the paper by Chojecki,
