The r-th generalized Hamming metric and the b-symbol metric are two different generalizations of Hamming metric. The former is used on the wire-tap channel of Type II, and the latter is motivated by the limitations of the reading process in high-density data storage systems and applied to a read channel that outputs overlapping symbols. In this paper, we study the connections among the three metrics (that is, Hamming metric, b-symbol metric, and r-th generalized Hamming metric) mentioned above and give a conjecture about the b-symbol Griesmer Bound for cyclic codes. we explore the combinatorial function of the size of the b-symbol weight set of a code C.
