_Maybe. The above argument applies to Stedman as well._ 

_The peal of Stedman Triples without bobs rely on a set of 5 blocks of
two courses each, that are joined by 3 omits affecting 5,6,7._ 

_The first block starts from rounds 2.3.5.6.7.8.9... the sixes between the
omits at 1 and 4 being irregular._ 

_This is a completed Q set, even though some of the sixes are irregular._ 

_In principle, complete Q sets are not required for Stedman Triples
either, but no such bobs only peals have ever been found._ 

_My point was that it might be better to look for complete Q sets with
irregular sixes in Erin._

 Sorry, clearly I meant:
 1234567 is bobbed, and 1234675 is plained. This means that 1234756 can
not be had AT A SIX END, but surely 2314756 or 3124756 can be, thus making
the q set rule redundant in this case.
