C# - 81bytes81 (161bytes * 0.5)

Simple job in C#, hopefully gets the no-neibouring-numbers bonus. Reads an int from stdin, writes out an array like the example to stdout.

class P{static void Main(){int n=int.Parse(System.Console.ReadLine()),m=n-1,i;var R="["+n;for(;m-->0;)for(i=m;i++<n;)R+=", "+i;System.Console.WriteLine(R+"]");}}

More readable:

class P
{
    static void Main()
    {
        int n=int.Parse(System.Console.ReadLine()),m=n-1,i;
        var R="["+n;
        for(;m-->0;)
            for(i=m;i++<n;)
                R+=", "+i;
        System.Console.WriteLine(R+"]");
    }
}

Examples output:

n = 5
[5, 4, 5, 3, 4, 5, 2, 3, 4, 5, 1, 2, 3, 4, 5]
