comment Examples of graph properties characterized by forbidden (not necessarily induced) subgraphs
In the case of graphs on surfaces we get a finite list of graphs so that a graph which is cannot be embedded must contain a subdivision of a graph from the list.

comment How to find ICM talks?
Quid, beside ICM and ECM what are other major congresses/conferences with major proceedings that we can ask about? (I could think also of INTERNATIONAL CONGRESS OF MATHEMATICAL PHYSICS (ICMP)), I am worry that a completely open-ended question will not be so useful without careful management.

comment How to find ICM talks?
I am not sure about asking and answering my own question as you suggested, Quid. If you want to ask this, or a more general question, I will be happy to answer. Meanwhile it can be a nice supplement here.

comment Grassmann-Plücker relations for permanents
Dear Abdelmalek, many thanks for the answer. You wrote "Set theoretic equations (of degree d+1) were discovered by Brill and Gordan." Can you elaborate on these equations?

comment A question about pairs of lines in 3D projective space
Thanks, David. Yes this is correct. But we can identify the quaternions with 2 dimensional v.s. over the complex so we get 8 choose 4. and then we can save a bit by intersecting with a generic hyperplane and get 7 choose 3. I wonder if Amitsur's theorem is relevant.
