I estimate median, modified dynamics (MOND) M / L values for recently published catalogs of galaxy groups. While the median, Newtonian M / L values quoted for these catalogs are 110-200 h 75 ( M / L ) ☉ , the corresponding values for MOND are less than 10 ( M / L ) ☉ (where the mass includes contributions from galactic and intragroup gas).
