I think that executing that S-box twice would get you back where you started. gijobarts (talk) 05:28, 30 July 2013 (UTC)

Actually that's not true. Regardless of the bit in position 1 to begin with, you will always have a 1 in position 8 in the result. When you shift, you're adding a 0 in position 1 (assuming a 0 shift in), then the inverse is 1, and flipping would put the 1 in position 8. Jarod997 (talk) 14:06, 5 March 2014 (UTC)
I was expecting the last bit to wrap around to the front. It could go either way. gijobarts (talk) 05:57, 6 March 2014 (UTC)

" and so is the author Randall Munroe at PyCon"

I think that post is a joke.
  • It links to 541: TED Talk.
  • It says "Registration volunteers have been instructed to refuse admission to Randall Munroe personally, and in fact, to any stick figures who may attempt to register"
  • There isn't anything on YouTube or Randall Munroe's Wikipedia page about it.
  • Another Python blog says that it was a publicity stunt, citing the organizers' mailing list archives. I didn't bother to sign up for access to the archive.
Catherine Devlin claims that she banned Randall, so we could try asking her if she's serious.
Another blog post about it
