I think the original paper is

@Article{flm:Wilkinson+Rogers:1973,
  author       = {G. N. Wilkinson and C. E Rogers},
  title	       = {Symbolic Description of Factorial Models for
                  Analysis of Variance},
  journal      = {Applied Statistics},
  year	       = 1973,
  volume       = 22,
  pages	       = {392--399}
}

but I don't have a copy of the paper, so I don't know what's in there.

best,
