From March '86 Scientific American:

  "... during the Christmas Holidays, James B. Shearer of the IBM
  Thomas J. Watson Research Center programmed an idle computer to
  search exhaustively for rulers, and the computer has now turned
  up Golomb rulesr with 14 and 15 marks.  The 14-mark Golumb ruler
  is 127 units long and has marks at 0, 5, 28, 38, 41, 49, 50, 68,
  75, 92, 107, 121, 123, and 127.  The 15-mark ruler is 151 units
  long and has marks at 0, 6, 7, 15, 28, 40, 51, 75, 89, 92, 94,
  121, 131, 147, and 151.  Shearer writes that he saved much computing
  time by assuming the middle mark on the ruler is to the left of
  the geometric middle."
