A while ago I tooted about languages such as #rexx and #ooRexx getting the "Hitchhiker's number" 2**276709 correct out of the box. That agrees with the Kindle book. Must dig out the paperback.

Now I've just played the radio shows from the boxed set of CDs (of series 1 to 5) and it says 2**267709 instead.

I'll play the 3 CDs of the version re-recorded for vinyl next, but the question is "How many versions of #h2g2 are there?"
