Appears in sequences

• Solution of the complementary equation a(n) = 2*a(n-1) + b(n-2), where a(0) = 1, a(1) = 4, b(0) = 2, b(1) = 3, and (a(n)) and (b(n)) are increasing complementary sequences.at n=16A295059
• a(n) is the smallest b >= 2 such that b^(6*2^n) - b^(3*2^n) + 1 is prime.at n=16A298206
