## Analytical formula?[edit]

Hi, the task needs the analytical formula to be stated as part of the task description rather than leaving it to be discovered. --Paddy3118 15:53, 4 January 2013 (UTC)

- I've watched the lecture; the problem in question is in the last 10 minutes and is only mentioned in passing. IIRC, it is at about 1:32:00 (and I forgot to note it down). If you've got the time though, it's
*well*worth watching the whole thing, and the mathematics involved is extremely simple (yet talks about some very interesting properties of sequences). –Donal Fellows 10:54, 9 January 2013 (UTC)

## Is there an relation to 100 prisoners?[edit]

[100 prisoners]

Here is the the task, to calculate the propability of finding a cycle/reoccurence of n?
In 100 prisoners you start with number n and hope to find n again.
