	OFFSET	`1,2`
	COMMENT	`Let (3^k-1)/2 = r then a((3^k-1)/2) = a(r) = 1 and a(r-1) = r. Geometrical interpretation. The sequence is obtained by the following rule: A point moves on the positive number line with the rule that in every step it has to move one unit more than the previous step and with the aim that it is to be as close to 0 as possible but on the positive side.`
	CROSSREFS	`Cf. A005132.` `Equals 1+A008344(n).` `Sequence in context: A059573 A080427 A118906 this_sequence A124037 A090285 A047908` `Adjacent sequences: A085056 A085057 A085058 this_sequence A085060 A085061 A085062`
