  • Starting from Season 8, Thirty begins taking on a prominent role similar to Twenty, where she sometimes appears as the biggest multiple of ten. This is because the twenties are all figured-out.
  • She is the first super-duper rectangle to appear in the show having 8 factors.
    • However, she was never revealed to have eight arrays until Season 8, which is after Twenty-Four was introduced.
