Editorial Comment:  I remember reading Harvey Bialy’s article on “The I Ching and the Genetic Code” in the magazine IO back in the day.  64 codons in DNA to describe amino acids, 64 changes in the I Ching.  The essay is available in the IO Anthology https://www.northatlanticbooks.com/shop/io-anthology/
