• Number of permutations of 1..n with no adjacent elements within 5 in value.at n=14A179959
• Number of permutations of 1..2*n+4 with no adjacent elements within n in value.at n=5A179962
• 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=42A185718
