[r-t] Doubles methods with two hunts and a plain course of 120

[Robert Bennett]

D'oh ! I wrote the place notation wrongly at the singles. Should have been
145. 

5.1.3.5.3.5.3.145.3.5.1.5.3.145.3.5.3.5.3.1 

 Too late in the evening (NZST)! 

These two hunt systems can be worked out using a 5x5 grid to represent the
relative positions of the two hunts. The diagonal is of course blocked off,
as the two bells should not be in the same place at once. 

Thanks Don for pointing out my muddle.

 I'm confused. By my reckoning this place notation leads to 35421, not
 12453 as claimed:

 12345
 21435
 24153
 42135
 24315
 42351
 24531
 42513
 45213 

54231
 45321
 43512
 34152
 43125
 41325
 14352
 41532
 14523
 41253
 14235
 12453
 --------
 21

 What am I missing?
