      "explanation": "No argument connecting these hypotheses to arithmeticity is supplied. The assertion includes nonuniform lattices and lattices with torsion: neither cocompactness nor torsion-freeness is assumed. A proof must therefore cover finite-volume orbifolds as well as manifolds, and all eligible subspace dimensions, not only hypersurfaces."

      "source_quote": "In this paper, a totally geodesic subspace of a finite volume hyperbolic manifold or orbifold will always mean a properly immersed, topologically closed, totally geodesic subspace. A totally geodesic subspace is \\emph{maximal} if it is not properly contained in another proper totally geodesic subspace.",
      "explanation": "These restrictions must be retained when checking any subsequent geometric or dynamical reduction. Under the usual convention of counting distinct geometric images, dimensions n <= 2 cannot provide infinitely many such subspaces of dimension at least 2: lower ambient dimensions exclude them, and in dimension 2 the only possible full-dimensional image is the ambient space. This elementary observation does not address n >= 3. The packet supplies neither the definition of arithmeticity used nor the reductions needed in those dimensions."
