Numbers k such that k² divides 15^k-1. A128395

Triangle read by rows in which row n gives coefficients of polynomial R_n(y) that satisfies R_n(1/2) = 8ⁿ, where R_n(y) forms the initial (n+1) terms of g.f. A097182(y)ⁿ⁺¹. A97181

Volume of elliptic cone (rounded down) with semi-minor axis = height = n and semi-major axis = 3·n/2. A228391

Consecutive states of the linear congruential pseudo-random number generator (421·s + 17117) mod 81000 when started at s=1. A385338

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
