COMMENTS

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 numbertheoretical sequence A007468. The other two are now A199714 and this sequence.
The synodic rotation period of the mainbelt asteroid (6572) Carson, discovered 1938, is approximately 2.8235 hours. [Galad & Kornos]  Arkadiusz Wesolowski and Robert Israel, May 11 2018
