Hi, I am just learning some materials and struggling to find what the other octet is. I know the following: [itex]3 \otimes 3 \otimes 3 = 10 \oplus 8 \oplus 8 \oplus 1 [/itex] Now I understand the 10 and one of the 8's. But I am a little unsure of what the other octet and singlet is in terms of quarks. Is the other octet just an excited state of the other octet (higher spin)?? http://proj.ncku.edu.tw/research/articles/e/20080523/images/080408014859tzxABW.gif (This is the octet I already know) Thanks.
