Les, I believe I already wrote it here. No, you cannot generate 5 vs. 1 TBs --
the main reason is that TB generator does not include 5 vs. 1 access code, and I
have no plan to sit down and write it. I'd better spend those hours on something
useful :-)

Even assuming that code is in place, system has not enough RAM (and probably
address space as well) to produce TBs other than ones with 3 identical pieces.
