OEIS Sequences

Numbers which converge to 2592 under repeated application of the powertrain map of A133500. A135384

Triangle read by rows: T(n,k) = number of j-covers of [n] with j<=k, k=1..2ⁿ-1. A369950

Expansion of g²/(1 - x³*g⁴), where g = 1+x·g³ is the g.f. of A001764. A391130

Fibonacci-like sequence of numbers with nondecreasing positive digits. Let a^+ denote the number that is obtained from a if its positive digits are written in nondecreasing order, while zeros remain in their places. Let a<+>b = (a + b)^+. a(0)=0, a(1)=1, for n>=2, a(n) = a(n-1) <+> a(n-2). A237568

a(n) = b(A074483(n), n), where b(k) is the recursion: b(1,n)=1, b(k+1,n)=b(k,n) + (b(k,n) reduced mod(k+n)) (cf. A074482). A74484

Integers k that have the property that there exists an integer·with n+1 digits, such that 1 <= k/x < 2 and k/x = 1 + (x-10ⁿ)/(10ⁿ-1), i.e., the same digits appear in the denominator and in the recurring decimal. A288782

Number of parts in all partitions of n in which no part occurs more than five times. A320608

Number of n-digit squares with no zero digits, having roots containing at least one zero. A104317

a(n) = prime(n)*prime(n+1) - prime(n+1). A37167

Triangle read by rows, characteristic polynomials of matrices; (n X n bisymmetric matrices in which both diagonals equal the (n-1)-th row of Pascal's triangle with the rest zeros). (n>=0, 0<=k<=ceiling(n/2)). A140693
