Supplementary Elliptic Curve Data

  1. Systematic coverage of all levels (as of March 2012):

  2. Tables of elliptic curves with good reduction outside certain sets S of primes. These were found using a magma program which is completely independent of modular computations. They are sorted by conductor (but not within each conductor); for conductors under 20000 the id code from the main table is given.

  3. Extra levels computed in May-August 2002 for Michael Bennett (with later additions for some larger levels). These were obtained using modular symbols as with the main table; only one curve for each isogeny class is given. N.B. These are now all in the main database.
