Query: Moduli Space of Cubic Surfaces as Ball Quotient via Hypergeometric
  Functions   We describe hypergeometric functions of Deligne-Mostow type for open subsets
of the configuration space of six points on P^2, induced from those for seven
points on P^1. The seven point ball quotient example DM(2^5,1^2) does not
appear on Mostow's original list, but does appear on Thurston's corrected
version. We show that DM(2^5,1^2) is a finite cover of the moduli space of
cubic surfaces M_C endowed with the ball quotient structure G_C\B^4 of Allcock,
Carlson, and Toledo. This answers a question of Allcock about the
commensurability of G_C with the monodromy groups of Deligne-Mostow
hypergeometric functions.
