 According to my reckoning the above PN works if instead of both 125s
 you have places in 145
 ie with the hunt bells being 1-2 there are 20 different positional
 relationships; in the above, the basic principle seems to be to work
 this out via slow sixes on the back three bells and to cut these sixes
 short where 1-2 would repeat positional relationship.

Correct. 

It occurs to me that the 3-part 120 of Grandsire Doubles  (SBSP x3) is a
method of this type.
