Layman's explanation wanted
You got it!
I have been trying to get CarlB's E8 to work for me but I cannot get the changes in color.
CarlB could help explain the E8 pattern better than me. ....
There are two things that need to be understood ... the E8 pattern and the Standard model.
Garrett put the two patterns together.
I'm at the stage of still trying to understand the finer points of symmetry.
Most of the discussions were on trying to understand how/why the patterns fit together or if the "rules" were being violated.
