- What is this number sequence?
- Will it contain arbitrarily large numbers? Prove it.
- Of the 1000 numbers shown here, the biggest number is 34, and it appears quite early. Is there any particular reason for that?
- Why does the sequence 6, 6, 6 appear in so many places? Does it have something to do with the devil?
- Will any other number ever appear three times in a row? Prove it.
- If you have plenty of spare time: Find the next number in the sequence.
- (hard) Near the beginning, there are a lot of twos. Will they eventually run out, or is there an infinite number of them?
