Random failure in elliptic_curves/constructor.py #16744
Comments
comment:1
It seems that this doctest is intended to illustrate that specifying "gens=" when cponstructing a curve from its label might be ignored when the curve is in the database. But there is a danger: the default database contains curves of conductors up to 10000 but does not contain their generators. So this is a test whose output will depend on whether or not the optional extended database is installed, something which we have been trying to avoid. I hope the authors of #11474 (not me!) will be able to say whether I have got this diagnosis right. |
