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

Number of collinear point-triples in an n X n grid. A938

Product of the cube of a prime (A030078) and a different prime. A65036

a(n) is the smallest k >= 2 such that k^2ⁿ+1 is prime, or -1 if no such k exists. A56993

Numbers n such that n¹⁰²⁴ + 1 is prime (a generalized Fermat prime). A57002

Multiples of 8 containing an 8 in their decimal representation. A121028

Number of integer partitions of n whose distinct parts are pairwise indivisible. A305148

Numbers m such that the Bernoulli number B_m has denominator 30. A51226

Write n in binary, then increase each run of 0's by one 0, and increase each run of 1's by one 1. a(n) is the decimal equivalent of the result. A175046

|First digit - second digit + third digit - fourth digit ...| = 10. A60978
