Query: Upper and Lower Bounds for Kronecker Constants of Three-Element Sets of
  Integers   Various upper and lower bounds are provided for the (angular) Kronecker
constants of sets of integers. Some examples are provided where the bounds are
attained. It is proved that 5=16 bounds the angular Kronecker constants of
3-element sets of positive integers. However, numerous examples suggest that
the minimum upper bound is 1=4 for 3-element sets of positive integers.
