• a(n) = ((3+sqrt(5))*(5+sqrt(5))^n + (3-sqrt(5))*(5-sqrt(5))^n)/2.at n=6A163065
• Totally multiplicative sequence with a(p) = 9p+2 for prime p.at n=39A166676
• Insert a dot after the first digit of a(n); this is now the beginning of the arithmetic mean of the digits used so far in the sequence. Lexicographically earliest sequence of distinct positive terms with this property.at n=15A335744
