OEIS Sequences

a(n) = ∑_i=1..n (-1)ⁱ⁺¹ prime(i)², where prime(k) denotes the k-th prime: alternating sum of the squares of the first n primes. A240860

Numbers k > 1 such that, in base 4, k and k² contain the same digits in the same proportion. A61658

Trace of Vandermonde matrix of numbers 1,2,...,n, i.e., the matrix A with A[i,j] = i^j-1, 1 <= i <= n, 1 <= j <= n. A60946

Numbers n such that n!8 + 2 is prime. A204663

a(n) = (n + 1)*(20·n² + 19·n + 6)/6. A220084

Sum of the second largest parts in the partitions of n into 6 parts. A308872

G.f. satisfies A(x) = 1 + x·A(x)³ + x³*A(x). A367057

Triangle read by rows: The n-th row is constructed by forming the partial sums of the previous row, reading from the right and if n is a triangular number repeating the final term. A99964

Triangle defined by g.f.: A(x,y) = exp( ∑_n>=1 xⁿ/n * ∑_k=0..n binomial(n, k)ⁿ * y^k ), as read by rows. A209424

Define g(k) = min(n: n >= 0, 2ⁿ + k prime). Then a(n) = min(odd k: g(k) = n). A260350
