| 2018-02-02 05:03:13 +0200 | asked a question | Listing fractions Hi, I would like to request help in listing rational numbers. For motivation, the command
outputs the integers from 1 through 9. Is there a similar command for listing out rational numbers a/b with a and b in the range (x1,y1) and (x2,y2), respectively. For instance, if a is in range (1,3) and b is in (4,6), I want to return
On a related note, how can one impose a gcd(x,y)==1 in the following list?

For instance, [(E.ainvs(), E.rank()) for E in cremona_curves(srange(a,b))] Can the same be done on sage with the Stein-Watkins database? |
