Query: Commensurability and arithmetic equivalence for orthogonal
  hypergeometric monodromy groups   We compute invariants of quadratic forms associated to orthogonal
hypergeometric groups of degree five. This allows us to determine some
commensurabilities between these groups, as well as to say when some thin
groups cannot be conjugate to each other.
