Excellent questions.
>> This might be a silly question but do at least parts 1 and 3
>> definitely have a solution? Or might the answer be no to
either/both?
If either 1 or 3 does not have a solution then it would resolve a famous
60-year old mathematical problem, the Lovasz conjecture for Cayley graphs
http://en.wikipedia.org/wiki/Lov%C3%A1sz_conjecture
A proof that either was impossible would make you famous (in
mathematics). I think it's more likely that there are solutions to both
1 and 3, but I don't know.
> Perhaps we should define question 0:
> 0. define 'good' ??
That's bound to be subjective, but what I have in mind is something that
it would be fun and practical to ring as a peal.

>> 2. Find a good one.
>> 3. Find an extent using only the three place notations 1,7,345.
>> 4. Find a good one.
