 OFFSET 1,1 COMMENTS It appears that the first differences of this sequence are always a multiple of 9. - Robert Price, Oct 20 2019 LINKS Table of n, a(n) for n=1..51. Index entries for sequences related to Reverse and Add! EXAMPLE The trajectory of 909 is part of the trajectory of 108; the trajectory of 126 joins the trajectory of 108 at 4069593 after 12 steps. MATHEMATICA limit = 10^3; x = NestList[ # + IntegerReverse[#] &, 108, limit]; Select[Range[909], Intersection[NestList[ # + IntegerReverse[#] &, #, limit], x] != {} &] (* Robert Price, Oct 20 2019 *) CROSSREFS Cf.
