<br>> The name "Stedmonster" seems to be in currency in certain places where
<br>> it is rung.
<br>>
<br>> I think the method has been discussed before, but so far as I know it
<br>> was open whether an extent was possible. It turns out that it is not so
<br>
<br>> hard to find one, although it would not be exactly easy to ring.
<br>
<br>This method was one of the ideas I discussed in the Christmas issue of
<br>The Ringing World, issue 5669/5670, p.1246
<br>(subscriber link: https://bb.ringingworld.co.uk/issues/2019/1246)

<br>
<br>I pointed that in Campanalogia (1677), p.168, Fabian Stedman says:‘ ‘Tis
<br>plainly demonstrable, that [t]he Principle upon five may go 420 triples
<br>upon seven, which is a twelfth part; 840 which is a sixth part; or 1260
<br>which is a fourth part of the whole, and the utmost period of triple
<br>changes. And then by making four extreams it may go 5040, the complete
<br>peal.’
<br>
<br>From the article:
<br>
<br>"Hunting on five, not three
<br>
<br>Another idea is to vary the six structure such as plain hunt and reverse
<br>plain hunt to be on five, not three. This gives sections of ten rows
<br>instead of six.
<br>&5.1.5.1.7.5.1.5.1.5,1
<br>The line is like an extended Stedman front work with hunting and points on
<br>the front 5, with quadruple dodges at the back. This gives a 140 change
<br>plain course, so to extend to 420 needs a bob. Changing a 7 to a 5 will
<br>not work, as it is next to another 5. Changing a 1 to a 3, or a 5 to a 3
<br>or 5 to a 7 could work. For symmetry these should be in the middle of a
<br>slow or quick ten. It is quite easy to generate a 420, 840 or 1260 with
<br>calls changing a 5 to a 7 in the fourth or seventh slow ten of a course,
<br>e.g. the following three parts: 420: 7 or 820: 7;4,7 or 1260: 7;7;4,7. I
<br>cannot see an easy way of generating a 5040 with four extremes, and a peal
<br>in whole courses is unlikely as I have only found 19 mutual true courses,
<br>but 36 would be required. As a curiosity this extends to higher numbers,
<br>either with more dodging pairs behind, or with hunting on 7 or 9."
<br>
<br>I didn't consider the bob you chose "- = 3 for 7" as I was trying to get a
<br>simple 420, 840 or 1260. Can you find a 5040 with 4 extremes?
