Query: Construction of three classes of Strictly Optimal Frequency-Hopping
  Sequence Sets   In this paper, we construct three classes of strictly optimal
frequency-hopping sequence (FHS) sets with respect to partial Hamming
correlation and family size. The first class is based on a generic
construction, the second and third classes are based from the trace map.
