Numbers k such that lcm(1,2,3,...,k)/13 equals the denominator of the k-th harmonic number H(k). A112818

Numbers divisible by at least five of their digits, different and >1. A187533

a(n) = prime(n)*(prime(n+1) + 1). A123134

Denominators of continued fraction convergents to sqrt(305). A41575

Number of base 16 n-digit numbers with adjacent digits differing by three or less. A126484

Array read by antidiagonals: the number of directed elements with area n on the lattice T_2k+1. A296129

For positive n with prime decomposition n = ∏_j=1..m (p_j^k_j) define A_n = ∑_j=1..m (p_j*k_j) and B_n = ∑_j=1..m (p_j^k_j). This sequence gives those n for which A_n and B_n are both prime and B_n = A_n + 2 (i.e., form a twin prime pair). A185718
