5x expanded by David Eppstein (talk). Self nominated at 04:18, 8 September 2014 (UTC).

  • New enough (5x expanded on 7 September), long enough (2,543 characters). Fully referenced. Image licensed okay. Hook fine, verified against online source. QPQ done. Good to go! Hawkeye7 (talk) 20:31, 8 September 2014 (UTC)
