This sequence has been calculated from the table of 440 lines in the link of A327157 of _Antti Karttunen_. That table contains the numbers in 122 complete cycles and in 5 incomplete 2-cycles with values larger than number 27287260 in line 440 which results in the cumulative sum of 445 for the data listed in this sequence. %H A336218 Hartmut F.
