[r-t] RE: Exceptions to the Extension Rules

[Edward W Martin]

Regarding Carters where Graham says:


Group 2. Invalid extensions with the same name
- Carter Doubles vs Triples, Caters, Cinques



Allowing for rotations,I believe that anyone asked to ring Reverse Stedman
would expect the following on all odd numbers from 5 on up:

N-2, N, 1, N-2, N,N-2, N,N-2, 1, N,N-2, N

However,

Carter's on all odd numbers from 5 on up is :

3 N 1 3 5 3 5 3 1 N 3 5

not

N-2, N, 1, N-2, N,N-2, N,N-2, 1, N,N-2, 1.

How can this be an invalid extension ?
