El_ka why this solution is not right? [2] // Problem 1789. Searching for the Dodecahedron 20 Jul 2011 14:54

If to walk from 2nd pedestal toward (n-1)th pedestal and to touch dodecahedron on each pedestal twice?
F.e.:
n = 7
answer:
10
2 2 3 3 4 4 5 5 6 6
Can somebody give me an example demonstrating this way is wrong?

For example,

n = 4

2 2 3 3 won't work when the stone at 4

The final stone will be 4->3->2->1->2 for example
