Appears in sequences

• Revert transform of (1 + 2x - x^2)/(1 + 3x + 2x^2 + x^3).at n=12A049131
• Initial term in sequence of four consecutive primes separated by 3 consecutive differences each <=6 (i.e., when d=2,4 or 6) and forming d-pattern=[6, 4,2]; short d-string notation of pattern = [642].at n=30A078855
• Primes of the form 6n^2 - 2n - 1.at n=25A099007

• G.f.: exp( Sum_{n>=1} A002426(n)^n * x^n/n ), where A002426(n) is the central trinomial coefficients.at n=4A168599
• Primes in A002049.at n=18A185846
• Primes of the form (2^n - 1)*(2^(m+2)) + 3 where n >= 1, m >= 1.at n=13A224383
• Primes in the union of all n-step Lucas sequences.at n=34A227885

• (2,3,5,7)-primes (see comments for precise definition).at n=22A262728
• Decimal representation of the x-axis, from the origin to the right edge, of the n-th stage of growth of the two-dimensional cellular automaton defined by "Rule 182", based on the 5-celled von Neumann neighborhood.at n=15A279697
