COMMENTS
{0, 6, 8} is by far the most frequent possible outcome for the numbers in this sequence (almost 60% of all cases up to 10^4, next most frequent being {0, 2, 6} and {0, 4, 6} and {0, 4, 8} in about 8% of the cases each). Up to 10^4, no term in this sequence can ever produce a 3. - M. F. Hasler, Apr 08 2023
