### Description

With sage-8.9.beta9, the command

sage -t --optional=sage,internet src/sage/databases/oeis.py

gives

keeping from 0 to 6 would have been enough I think, but let's go with 11.

**Note:**See TracTickets for help on using tickets.

Since the number of cross-references will keep increasing (which is good), i added some dots to avoid useless updates. With 11 references, there is more than enough to show the feature.
