Query: Arithmetic and topology of classical structures associated to plane
  quartics   We consider moduli spaces of plane quartics marked with various structures
such as Cayley octads, Aronhold heptads, Steiner complexes and G\"opel subsets
and determine their cohomology. This answers a series of questions of Jesse
Wolfson. We also explore some arithmetic applications over finite fields.
