GA(n) is the general affine group, the automorphism group of the Reed-Muller code RM(r,n).
Since the group is triply transitive, there's only one orbit for vectors of weight 0,1,2,3.
EXAMPLE
Triangle begins:
1 1
1 1 1
1 1 1 1 1
1 1 1 1 2 1 1 1 1 (the 2 is because there are two orbits on vectors of length 8 and weight 4)
1 1 1 1 2 2 3 3 4 3 3 2 2 1 1 1 1
