Appears in sequences

• Expansion of (2-4*x+x^3)/((1-x)*(1-2*x-x^2+x^3)).at n=13A052949
• Diagonal sums of number array A082110.at n=14A082114
• Write down the numbers from 3 to infinity. Take next number, M say, that has not been crossed off. Counting through the numbers that have not yet been crossed off after that M, cross off every 5th term. Repeat, always crossing off every 5th term of those that remain. The numbers that are left form the sequence.at n=40A100586
• a(n) = 14*n^2 + 1.at n=37A158482
• a(n) = 56*n^2 + 1.at n=19A158660
• Maximum fixed points under iteration of sum of cubes of digits in base n.at n=20A226026
• Prime time numbers on 6-digit clocks: numbers of the form HMMSS where H, MM, SS are primes, H < 24, MM and SS < 60.at n=6A295014
• a(n) = A335175(n) + A335176(n).at n=3A335177
