- 16:48 Bug #994: SEGV: Toric example from Kazuki Maeda
- definitively a bug: "n" instead of "Indices[n]" in the preprocessing.
Obviously a very rare case.

- 11:00 Support #1031 (New): ScalarProduct: exact defn and manual page
- We must establish the exact definition of *@ScalarProduct@* and rewrite the manual page accordingly.
