Sage Days 49: Free and Practical Software for (Algebraic) Combinatorics, June 17th-21st, Orsay

FPSAC 2013 (Formal Power Series and Algebraic Combinatorics) is the main yearly international conference in algebraic combinatorics. It will happen this year in Paris, June 24th-28th. We are organizing a Sage-Combinat Days as a satellite event the week before:

Sage Days 49: Free and Practical Software for (Algebraic) Combinatorics

Orsay (south west suburb of Paris)

June 17th-21st 2013

Tentative Schedule

  • Monday-Wednesday morning: tutorial for newcomers and talks with a slant toward algebraic combinatorics
  • Rest: coding sprints

Newcomers are welcome to join later in the week; there won't be specific events organized for them then, but we will be available for questions and discussions while they get through tutorials on their own or work on their personnal projects.


The workshop will be held at the Faculté d'Orsay, probably in the math department. It's 45 minutes from Paris downtown by local trains, and a five minute walk from the hotel (see below).


See the Projects list.


Participation is free. To register, please fill in this poll so that we can plan ahead for rooms, coffee breaks, ... and also to optimize the lodging. Please send us your e-mail address as well so that we can get in touch with you as the workshop gets closer.


We have negociated a reduced price at the nearby Residhome Appart Hotel from Bures-sur-Yvette. The rate is of 66€ per night (56€ 5 nights or more) for a two person studio (double bed or twin bed). There is also a reduced rate of 106€ (90€ for 5 nights or more) for a four person apartment (two double beds; probably not so convenient). Breakfast is not included; see the web site for the amenities.

To reduce the expenses you are strongly encouraged to find a room mate to share a double room with. In particular, for those person that will get funding from us for lodging, we will most likely reimburse on the basis of 33 euros per night in order to support more participants.

To reserve a room, please send them an e-mail at or call +33 1 64 86 36 00. Mention that you come for the "Sage Days 49 conference". If you want to share a twin room, mention it and specify who your room mate will be.

Caveat: there are only a limited number of rooms with twin beds, and they will run out soon. Therefore you are urged to reserve your room as soon as possible.


For participants coming from universities in the United States, there is funding from our Sage-Combinat NSF grant. Please email Anne Schilling (email anne at with your CV and an estimated budget. The deadline for this is March 30, 2013. Later applications will be considered as long as funds are available.

For now this all you need to do to request funding.

Why 49?

Because that's 7^2

Why Orsay?

“Be grateful you’re not in the forest in France

Where the average young person just hasn’t a chance

To escape from the perilous pants eating plants

But your pants are safe, you’re a fortunate guy

You ought to be shouting how lucky am I”

-- Dr. Seuss, Did I Ever Tell You How Lucky You Are?
