[r-t] Cinques focus

[Philip Earis]

Sorry, just catching up on what's been happening. I am rather thrilled to see some new Cinques being rung -Alan Reading has put together a cyclic composition of spliced "Nirerin" and Erin Cinques - http://www.bb.ringingworld.co.uk/view.php?id=320841. it's pleasing to see some 11-bell innovation rather than falling back on the tired old diet of Stedman.

Nirerin Cinques is a rather nice principle with 10-change sections: 9.E.9.E.9.3.1.3.1.3 = 241638507E9, leading to double-dodging in 3-4, 4-5, 5-6 and so on.  The method has glide symmetry, well employed here, and it looks like the composition suitably and simply exploits the regular coursing musical properties.

I'm a bit puzzled about the choice of name, though.  "Nirerin" as a word seems to be a palindromic play on "Erin", but palindromic symmetry is something that the method NIrerin lacks?
