Is there a representation diagram for fermions like the 8 fold way for mesons?

I was wondering if there was something similar to the 8 fold way representation used on mesons for the fermions?

Well... no.
What did you have in mind?

But then - "fermions" is such a large group, including quarks and leptons.
If you just mean baryons ("the other hadrons"), then there's a decouplet which is kinda like the eight-fold way for mesons.

of course

there is are two triangle-diagrams for the two fundamental triplet (quark and antiquark) representations of SU(3) http://universe-review.ca/I15-38-8foldway.jpg

and there are the baryon octet and decuplet diagrams http://en.wikipedia.org/wiki/Eightfold_Way_(physics)

assuming you are talking about 3 flavours, otherwise it becomes more complex (e.g. for 4 flavours) http://static.wix.com/media/d3fcbc01...cd99333.wix_mp

Brilliant, thanks for the links.
