OEIS Sequences

List of totally balanced sequences of 2n binary digits written in base 10. Binary expansion of each term contains n 0's and n 1's and reading from left to right (the most significant to the least significant bit), the number of 0's never exceeds the number of 1's. A14486

Narayana's cows sequence: a(0) = a(1) = a(2) = 1; thereafter a(n) = a(n-1) + a(n-3). A930

Number of primes p between powers of 2, 2ⁿ < p <= 2ⁿ⁺¹. A36378

Numbers k such that k! + 1 is prime. A2981
