Croissants

I recently gained entry into the On-line Encyclopedia of Integer Sequences for the the sequence 1, 3, 7, 19, 55. It's probably the only entry in the Encyclopedia with a reference to Mastering the Art of French Cooking, Volume Two and priority should be assigned to Childs and Beck, but the sequence is also musically interesting. It suggests a family of tunings including 1/3-comma temperament (close to 19-tet) and the 55-tone temperament said to be favored by Telemann.
