a) Stages at which an extension of a method exists are a finite set,
plus an infinite arithmetic series (possibly omitting stages where the
cycle lengths have certain factors - these in turn form infinite
series). The step in the series has no factors that are prime powers
exceeding the number of working bells.
b) The proportion of methods at a given stage that have valid extensions
tends to zero as the stage increases.
c) The ratio of the number of methods that have valid extensions to the
additional number that would be valid without (G)B1 tends to infinity as
the stage increases.
