Résumé : The Janko group J1 has, up to duality, exactly two regular rank four polytopes, of respective Schläfli types {5, 3, 5} and {5, 6, 5}. The aim of this paper is to give geometric constructions of these two polytopes, starting from the Livingstone graph. © Springer Science+Business Media, LLC 2011.
