The Jessen–Marcinkiewicz–Zygmund Theorem implies that the maximal operator associated with a Soria basis continuously maps <i> L </i> log² <i> L </i> into <i> L </i> ¹,∞. We give a simple geometric condition that guarantees that the <i> L </i> log² <i> L </i> class cannot be enlarged. The proof develops the author’s methods applied previously in the two-dimensional case and is related to theorems of Córdoba, Soria and Fefferman and Pipher.</div>
