• For positive n with prime decomposition n = Product_{j=1..m} (p_j^k_j) define A_n = Sum_{j=1..m} (p_j*k_j) and B_n = Sum_{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).at n=46A185718
• T(n,k)=Number of n-step one space for components leftwards or up, two space for components rightwards or down asymmetric quasi-queen's tours (antidiagonal moves become knight moves) on a kXk board summed over all starting positions.at n=51A187857
• Number of 7-step one space for components leftwards or up, two space for components rightwards or down asymmetric quasi-queen's tours (antidiagonal moves become knight moves) on an n X n board summed over all starting positions.at n=3A187862
• Number of n X 3 arrays of the minimum value of corresponding elements and their horizontal, diagonal or antidiagonal neighbors in a random, but sorted with lexicographically nondecreasing rows and columns, 0..1 n X 3 array.at n=27A219514
• Number of partitions of n with difference -7 between the number of odd parts and the number of even parts, both counted without multiplicity.at n=49A242685
• Numbers k which are the product of a cube greater than 1 and a prime, and where k-1 and k-2 are semiprimes.at n=40A350284
• a(n) = sum of the origin-to-boundary graph-distances of all partitions of n.at n=30A368986
• Numbers k such that 2^k, 2^(k+1) and 2^(k+2) have the same number of terms in their Zeckendorf representation (A007895).at n=4A374961
