(c) the order in which candidates in different preferenced groups are numbered is worked out by reference to the order in which the groups were numbered on the ballot paper, starting with the group marked 1; and
(d) when all the candidates in a preferenced group have been
numbered, the candidate whose name is at the top of the next preferenced group
is given the next consecutive number.
