Results including tables 3 of the best-known quaternary Hermitian LCD codes of any length n ≤ 25 with corresponding dimension k are presented.  ...  In addition, Many of these quaternary Hermitian LCD codes given in this paper are optimal which are saturating the lower or upper bound of Grassl's codetable in and some of them are nearly optimal.  ...  Acknowledgements This work is supported by the National Natural Science Foundation of China under Grant No.11801564.  ...
