2 3 1 2 1 3 (Posted on 2004-11-23) Difficulty: 3 of 5

If two 1's, two 2's and two 3's are arranged thus:

2 3 1 2 1 3

then the two 1's enclose 1 other digit, the two 2's enclose 2 other digits, and the two 3's enclose 3 other digits.

Can you find a similar arrangement using the seven pairs 1,1,...7,7?
