Hi Eric, Looks like a(6078) = 8945 is the last term of your sequence. According to my calculations the last terms ending with 0-9 digits are: a(5914) = 5890 a(6060) = 8201 a(6064) = 8302 a(6073) = 8613 a(6075) = 8734 a(6078) = 8945 a(6059) = 7756 a(6067) = 8563 a(6051) = 6778 a(5918) = 5979 It is easy to see that there will be no additional terms.
