Map 62 Hexagrams 64 Codons in only 39 Hexagrams

Hi this is a map of hexagrams showing all 64 hexagrams read in back to front, up and down and diagonally using the same letters over and again so that all 64 hexagrams 3 letter codons can be found with the least amount of hexagrams. This 39 is my smallest to date but I will keep on trying to reduce it. I also have three empty hexagrams amongst them which I need to try to be rid of.

I have just noticed an error in this map I have repeated CAG twice so this is no longer the smallest map I have been able to create. Another go at this required. Do let me know if you manage it in less.

THIS HAS NOW BEEN REDUCED TO 36 Triangles
