OEIS Sequences

Arrange digits of cubes in ascending order. A32553

a(0) = 0, a(1) = a(2) = 1, a(3) = 2, a(4) = 4, for n>3: a(n+1) = SORT[ a(n) + a(n-1) + a(n-2) + a(n-3) + a(n-4)], where SORT places digits in ascending order and deletes 0's. A108565

Primitive subsequence of A111105. A137559

Semiprimes k such that k+2 and k+6 are primes and k+4 and k+8 are all semiprimes. A392186

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n+1-k), where k = [ (n+1)/2 ], s = (Fibonacci numbers), t = (composite numbers). A24461

a(n) = s(1)t(n) + s(2)t(n-1) + ... + s(k)t(n-k+1), where k = [ n/2 ], s = (Fibonacci numbers), t = (composite numbers). A25081

Numbers n such that 175·2ⁿ-1 is prime. A50839

a(n) = smallest M such that M is not divisible by prime(1), ..., prime(n), but is divisible by ∑_i=1..n (M mod prime(i)); or 0 if no such M exists. A106572
