The database of elliptic curves over $\Q$ consists of the following sets of curves:

- all curves of conductor less than $500,000$;
- all curves whose conductor is $7$-smooth (that is, only divisible by primes $p\le 7$;
- all curves of prime conducto r$p \le 200,000,000$.

Currently, the database includes $3,824,372$ elliptic curves over $\Q$ in $2,917,287$ isogeny classes, with conductor at most $299,996,953$.
