| Feb 21 at 10:34 | comment | added | psmears | You can actually make this work even if the outer two skulls can be swapped - because swapping positions (1,3) is the same as swapping (1,2) then (2,3) then (1,2) again, and your reasoning isn't affected by the difference :) | |
| Feb 20 at 14:58 | comment | added | akostadinov | That's easiest to understand and remember. Issue is I doubt I can count precisely the number of swaps :( | |
