 A118879 Let T(S,Q) be the sequence obtaining by starting with S and repeatedly reversing the digits and adding Q to get the next term. This is T(1016,5), the first S for which T(S,5) reaches a cycle of length 36. 3
 1016, 6106, 6021, 1211, 1126, 6216, 6131, 1321, 1236, 6326, 6241, 1431, 1346, 6436, 6351, 1541, 1456, 6546, 6461, 1651, 1566, 6656, 6571, 1761, 1676, 6766, 6681, 1871, 1786, 6876, 6791, 1981, 1896, 6986, 6901, 1101, 1016, 6106, 6021 (list; graph; refs; listen; history; text; internal format)
 OFFSET 0,1 COMMENTS The cycle is simply the first 36 terms, which then repeat. For S < 1016, T(S,5) reaches a cycle of length 207 (cf. A117800). LINKS N. J. A.
