 OFFSET 1,2 COMMENTS Conjecture: This sequence is finite. Contribution from Artur Jasinski, Dec 08 2008: (Start) The EKG sequence A064413 has 3 critical lines. Numbers which belong to the critical lines: (1) A064413(n)=n see A152458, (3/2) 2*A064413(n)=3n see A152519, (1/2) 2*A064413(n)=n has only 2 numbers {10, 14}. Because points are concentrated on the plot of EKG sequence near these 3 critical lines, the number of points belonging to critical lines is surprisingly low. Is this sequence complete? (End) Also fixed points of A247379. - Reinhard Zumkeller, Sep 15 2014 LINKS PROG (Haskell) a152458 n = a152458_list !!
