## Main Question or Discussion Point

I am confused. I thought that the standard model included 6 quarks and 6 antiquarks, 6 leptons and 6 antileptons and 5 bosons (W+,W-,Z,photon,gluon).

However in Griffith's "Introduction to Elementary Particles" (on page 48) he says that there are "12 leptons, 36 quarks, 12 mediators".

I am thinking of the t,b,u,d,s,c and their antiparticles for the quarks.

So can someone please account for the remaining 24 quarks and the remaining 7 bosons?
