An example of the working, or not, of adjacency.
We take Kent TB6 - since everyone on this list will be familiar with it.
Above the treble, adjacency means that the 3-4 (typical Kent) places
above the treble in 1-2 must be preserved somehow. Some typical
Kent TB8: 3-4 places with treble in 1-2
Twatt TB8: 3-4 and 5-6 places with the treble in 1-2 and 3-4
MeyrickTB8: 5-6 and 5-6 places with the treble in 1-2 and 3-4 - in this
case, the adjacency has acceptably moved to treble in 3-4
Obnoxious TB8: 3-6 and 5-6 places with the treble in 1-2 and 3-4 - see
Meyrick note - an example of a modal extension
Windsor TB8: 5-6 places with the treble in 1-2 - no adjacent places so
