The prime polynomial used to generate GF(8) is: X³+X²+1. The element f=aX²+bX+c, a,b,c in {0,1}, is written as the number a*4+b*2+c.

The weight distribution (formal selfdual):

A'₀= 1, A'₈= 6678, A'₉= 26656, A'₁₀= 130928, A'₁₁= 512736, A'₁₂= 1524880, A'₁₃= 3197152, A'₁₄= 4878384, A'₁₅= 4517408, A'₁₆= 1982393.
