Sage-Combinat Days in Cernay, April 6-12, 2014

Cernay 2014, Sage Days 57

The fourth "Sage-Combinat Days in Cernay" will be held at Cernay-la-Ville (40km South-West of Paris, near Orsay), April 6-12, 2014.

Following the *-Combinat tradition we booked the guest house The Tower in Cernay-la-Ville. It is a very nice and cosy "gîte", 50 minutes from Paris by public transport.

This workshop is also "Sage Days 57". More Sage workshops are listed on the Workshops page of the Sage wiki.
