OEIS Sequences

Let Oc(n) = A005900(n) = n-th octahedral number. Consider all integer triples (i,j,k), j >= k > 0, with Oc(i) = Oc(j)+Oc(k), ordered by increasing i; sequence gives k values. A53678

Number of rationals in [0, 1) consisting just of repeating bits of period at most n. A119917

A triangular sequence of coefficients of polynomials: p(x,n) = ((x - 1)ⁿ *(∑_k>=0 (((-1)ⁿ*(2·k + 1)^{n - 1}))*x^k) + (x - 1)^{n + 1}*(∑_k>=0 ((-1)^{n + 1}*kⁿ)*x^k)/x)/2. A154334

E.g.f. satisfies A(x) = exp(-x·A(x)) * A( x·exp(-x·A(x)) )². A383560

Numbers k such that 197·2^k+1 is prime. A32475

a(1)=1, a(n) = the smallest integer > a(n-1) that is divisible by the number of divisors of a(n-1). A141452
