Ed's Note: For those not sure what an optimal Golomb ruler is, or how you would use one, see here.

"Following the recent start of the OGR-28 project, the search for the optimal Golomb ruler with 28 marks, distributed.net quietly announced the completion of project OGR-27 on February 25. The shortest Golomb ruler with 27 marks has length 553 and marks at positions 0 3 15 41 66 95 97 106 142 152 220 221 225 242 295 330 338 354 382 388 402 415 486 504 523 546 553. This confirms that the best known, up to now, Golomb ruler was optimal. When the project began, it was expected that a shorter ruler would be found, but this did not happen."
