- - ### Constructor Detail

    - #### Pos

          public Pos​(int _x,
                     int _y)

    - #### Pos

          public Pos​(int num)

      Parameters:
        `num` - in the [0 .. N*N-1] range

  - ### Method Detail

    - #### num

          public int num()

      Counted by row (left-to-right), rows being arranged bottom-to-top. In other words, the lexicoraphic order for the (y,x) pairs. The ordering for cells is 1-based.

    - #### bucketNo

          public int bucketNo()

      Converts the coordinates of a bucket to a bucket number.
      Returns:
        the bucket number, or -1 if the coordinates are not valid

    - #### norm2sq

          public int norm2sq​(Board.Pos q)

      Square of 2-norm distance

    - #### norm1

          public int norm1​(Board.Pos q)

      1-norm distance

    - #### flip2corner

          public Board.Pos flip2corner()

      Mirror image of this cell into the bottom left corner

    - #### nearestBucket

          public HashSet<Integer> nearestBucket()

      Which bucket(s) is/are the nearest to this cell?

    - #### remotestBucket

          public HashSet<Integer> remotestBucket()

      Which bucket(s) is/are the most remote from this cell?
