Other issues (with all other variables as their defaults):

• If all of 1024 cards are visible, the label says Infinity dots are visible
• If 1025 or more cards are generated, all cards have the infinity symbol as the number of dots on the card
  (limit before this happens in base-6 is 397, b-10 is 309, b-16 is 256)
• Would be nice if the total number of dots was comma-separated like how the numbers are on the cards themselves
• Sometimes with particularly small numbers there is an extra really small number of dots according to the total
• Under some circumnstances a card of some number of dots is rendered without any dots
