Query: Sharp Khinchin-type inequalities for symmetric discrete uniform random
  variables   We establish several optimal moment comparison inequalities (Khinchin-type
inequalities) for weighted sums of independent identically distributed
symmetric discrete random variables which are uniform on sets of consecutive
integers. Specifically, we obtain sharp constants for the second moment and any
moment of order at least 3 (using convex dominance by Gaussian random
variables). In the case of only 3 atoms, we also establish a Schur-convexity
result. For moments of order less than 2, we get sharp constants in two cases
by exploiting Haagerup's arguments for random signs.
