• a(n) = n^3 + 2.at n=41A084380
• a(n) = smallest M such that M is not divisible by prime(1), ..., prime(n), but is divisible by Sum_{i=1..n} (M mod prime(i)); or 0 if no such M exists.at n=22A106572
• Semiprimes of the form n^3 + 2.at n=20A259189
• Solution of the complementary equation a(n) = a(n-1) + a(n-2) + b(n-1) + 2*b(n-2), where a(0) = 1, a(1) = 2, b(0) = 3, and (a(n)) and (b(n)) are increasing complementary sequences.at n=18A294559
