 A104056 Each number is the rank in the alphabet of a letter (and "0" stands for a space). After substitution one reads (in English): "one five one four five zero six nine two two five zero ..." which is the succession of the digits of the sequence itself: 1 5 1 4 5 0 6 9 2 2 5 0... 3
 15, 14, 5, 0, 6, 9, 22, 5, 0, 15, 14, 5, 0, 6, 15, 21, 18, 0, 6, 9, 22, 5, 0, 26, 5, 18, 15, 0, 19, 9, 24, 0, 14, 9, 14, 5, 0, 20, 23, 15, 0, 20, 23, 15, 0, 6, 9, 22, 5, 0, 26, 5, 18, 15, 0, 15, 14, 5, 0, 6, 9, 22, 5, 0, 15, 14, 5, 0, 6, 15, 21, 18, 0, 6, 9, 22, 5, 0, 26, 5, 18, 15, 0, 19, 9, 24 (list; graph; refs; listen; history; text; internal format)
