%N Rearrangement of natural numbers so that every term is relatively prime to the sum of its neighbors.
%C If a(n) = k, define the dislocation of k to be Absolute[k-n]. Conjecture: The maximum value of dislocation < 5.
%C The conjecture first fails at a(169) = 164. In the first 18000 terms, the largest dislocation is 8. - _David Wasserman_, Jan 17 2005
