 OFFSET 0,5 COMMENTS The R5 dragon curve can be represented using an L-system. LINKS Rémy Sigrist, Table of n, a(n) for n = 0..3125 Kevin Ryde, Iterations of the R5 Dragon Curve Rémy Sigrist, Colored representation of the first 1 + 5^9 points of the R5 dragon curve (where the hue is function of the number of steps from the origin) Rémy Sigrist, PARI program for A349196 Index entries for sequences related to coordinates of 2D curves FORMULA a(5^k) = A006496(k) for any k >= 0. EXAMPLE The R5 dragon curve starts as follows: +-----+ 24| 25 | | +-----+ +-----+ +-----+ 23 22| 11| 10| 7| 6| | | | | | 21| 12| 9| 8| | +-----+-----+-----+-----+-----+ 20| 17| 16| 13| 4| 5 | | | | | | | | | | +-----+ +-----+ +-----+ 19 18 15 14 3 2| | | +-----+ 0 1 - so a(0) = a(1) = 0, a(2) = a(3) = a(14) = a(15) = a(18) = a(19) = 1.
