[r-t] Jump change notation

[Glenn Taylor]

Don,

FWIW, when Cambridge Jump was first published in the RW in about 1979 the
notation used was along the lines of:

-3-(4.2)-2 etc.

the "novelty" being that the bracketed part indicated that the next row was
the end result of applying 14 followed by 12. Whilst less mathematical and
perhaps a little more cumbersome than the notation used for permutations and
cycles, it does have the benefit of retaining current notation (apart from
the need to understand the purpose of the brackets) and thereby being
"accessible" to the non-mathematical interested party.
