Does it? If one member of a q set is bobbed and another plained, then the 3rd member cannot be obtained. but as we can start a six from any one of 3 places, surely the following can apply:
1234567 is bobbed, and 1234675 is plained. This means that 1234765 can not be had AT A SIX END, but surely 2314765 or 3124765 can be, thus making the q set rule redundant in this case.

If it were that straightforward I would have thought someone's computer would have already done it.
