%N A puzzle - explanation is not known.
%C In November 1987, an editor at the Astrophysical Journal wrote to _N. J. A. Sloane_ with three sequences whose explanation was not known to her. She said: "As to the pedigree of these sequences, not much is known. But they are US in origin, and /not/ Hungarian". One of the three was the number-theoretical sequence A007468. The other two are now A199714 and this sequence.
%C The synodic rotation period of the main-belt asteroid (6572) Carson, discovered 1938, is approximately 2.8235 hours. [Galad & Kornos] - _Arkadiusz Wesolowski_ and _Robert Israel_, May 11 2018
