For a single-phase experiment, we allocate treatments to
experimental units using a systematic plan, and then randomize by
permuting the experimental units by a permuation chosen at random from
a suitable group.   This leads to the theory developed in J. A.
Nelder's 1965 Royal Society papers.  Recently, C. J. Brien and I have
been extending this theory to experiments such as two-phase
experiments, where the produce, or outputs, from the first phase are
randomized to a new set of experimental units in the second phase.
This brings in new difficulties, especially with standard software.
