I do not believe it is possible in an email reply to provide you with an
explanation. However, after reading many articles and several books, I
came across Maxwell S.E. & Delaney H.D."Designing Experiments and Analysing
Data" Wadsworth 1990 which has a very simple and easily understood account
of the differences. I strongly advise you beg, steal or borrow a copy and
read about non-orthogonal designs in Chapter 7.

Regards,  Glen.
