[r-t] Parity

[edward martin]

It seems to me that however many bells are involved, there must be a
recurring pattern because  there are always groups of six rows where
the relationship between n-2, n-1 & n is being considered Thus,
depending on the initial parity , each group of six would either be
+ - - + + -
or
- + + - -+
