Assume the following (fake example) ordered list of randomness sources:
- The People's Democracy of Betastani State Lottery six winning numbers (ignoring the seventh "extra" number) for 1 October 1998.
- Numbers of the winning horses at Hialeia for all races for the first day on or after x September 1998 on which at least two races are run.
- The Republic of Alphaland State Lottery daily number for 1 October 1998 treated as a single four digit integer.
- Closing price of Example Corporation stock on the Lunar Stock Exchange for the first business day after x September 1998 when it trades.
