Query: On a conjecture for representations of integers as sums of squares and
  double shuffle relations   In this paper, we prove a conjecture of Chan and Chua for the number of
representations of integers as sums of 8s integral squares. The proof uses a
theorem of Imamo\={g}lu and Kohnen, and the double shuffle relations satisfied
by the double Eisenstein series of level 2.
