Here is a little question I don't recall hearing about before:
Find an IN-COURSE 120 of (pure) doubles, in which each in-course row
occurs once at hand and once at back. (Any such can of course be doubled
with a single to get a 240 with each row once at hand and once at back and
only two single changes).
I'm sure there are plenty of examples, but what about ones that can be
regarded as reasonably sensible methods?
