  • What is the best method of achieving the highest or the widest column with similar coins, or with different diameter coins?
  • How is the highest ratio, of height to number of similar coins, best achieved?
  • How is the largest ratio, of maximum column width to maximum column height, best achieved?
  • Conversely, how is the largest ratio of maximum column height to maximum column width, best achieved?
