<p dir="ltr">Simon Gay has posted an interesting blog piece about ringing surprise minor in hand: http://www.handbellringing.co.uk/blog/getting-started-with-surprise-minor</p>
<p dir="ltr">I'd like to explore one aspect further. Simon introduces the "4 possible [surprise] backworks" (Norwich, Cambridge, London, Carlisle), as well as "6 possible right-place frontworks" (though for some reason he doesn't include x34x56 or x12x56 or x12x16). Simon then says:</p>
<p dir="ltr">"In principle, any of these frontworks could be combined with any of the 7 backworks (two versions of each backwork, except London) to give a total of 42 methods. In practice, there are various ways in which some of these combinations might be undesirable:<br>
- The method might be false in the plain course.<br>
- The method might come round after fewer than 5 leads.<br>
- The method might not have Plain Bob lead ends."</p>
<p dir="ltr">My first question is: when does the first of these (false in the plain course) actually occur, ie when bolting a symmetric minor overwork onto a symmetric minor underwork? </p>
<p dir="ltr">More generally, what are the conditions that will lead to falseness in the plain course in a symmetric method with n-1 leads in the plain course? Or asymmetric (such as Richard's False Course minor, x4x3x3x23x4x1, for which a true 720 is possible)?<br><br></p>
