Create the shortest possible sequence such that no number is next to its first-hand or second-hand neighbors (e.g., the number 3 cannot be next to numbers 1, 2, 4, or 5, which are first- and second- neighbors).

No as there would be a number that could not be beside any other. For example in a sequence of numbers 1-5 the number 3 could not be beside any other number making a run of 5 (or less) impossible.is a 5 sequence possible?
