COMMENTS

Gives number of row in Wythoff array that contains n. - Casey Mongoven (cm(AT)caseymongoven.com), Sep 10 2005

Contribution from Clark Kimberling (ck6(AT)evansville.edu), Oct 29 2009: (Start)

For a method of generating this sequence that does not refer to the

Wythoff array or Fibonacci numbers, see A003603. (End)

FORMULA

Says which row of Wythoff array (starting row count at 0) contains n.

If delete first occurrence of 0, 1, 2, 3, ... the sequence is unchanged.

CROSSREFS

Equals A003603(n) - 1.

Cf. Wythoff array: A035513.

Sequence in context: A025648 A025655 A022336 * A176095 A063942 A106384

Adjacent sequences:  A019583 A019584 A019585 * A019587 A019588 A019589

EXTENSIONS

Casey Mongoven (CaseyBach(AT)aol.com) reports that where the sequence reads 15,9,2,16,10,6,29,1,30,11,7,19..., the 29 and 30 should be 17 and 18.
