- Invited speakers:
- October 13-15: Coding Sprints (chair Michael Abshoff)

Each "talk" day (October 10 to 12) typically has 2 invited speakers, who are specialists in the corresponding domain, not necessarily already in contact with SAGE, and 3 contributed speakers, who typically describe a SAGE module (or a proposal of).

The SAGE Days 10 dinner will take place on the 11th.
