The main reason for pn7 was that it produces the 7-part cycles from
the group PSL(2,7), through 14 rows of Plain Hunt. I suppose any other
negative involution strays from the group. But PSL(2,7) was definitely
the group I wanted to use, as it seemed the most well suited to the
job for various reasons.
I think there could be some nice alternatives using double/single
changes, though maybe more in the line of treble dominated methods.
112-row plain courses would be interesting to explore, and the
challenge of joining the 45 courses. Of course, the ideal would be to
have triple changes only but I imagine that's too much to ask.
