Abstract: For two distinct prime numbers p, q, we compute the rational cuspidal subgroup C(pq) of J0(pq) and determine the l-primary part of the rational torsion subgroup of the old subvariety of J0(pq) for most primes l. Some results of Berkovic on the nontriviality of the Mordell-Weil group of some Eisenstein factors of J0(pq) are also refined. © 1997 American Mathematical Society.
