• a(n) = 20*a(n-1) - 98*a(n-2) for n > 1; a(0) = 1, a(1) = 10.at n=5A162666
• Permutation trees of power n and height k.at n=51A179454
• Let x(0)x(1)x(2)... x(q) denote the decimal expansion of n. Sequence lists the numbers n such that the suffix of decimal expansion x(2)... x(q) is the p-th divisor of n where p is the prefix of decimal expansion x(0)x(1).at n=17A234315
• a(n) is the sigma irregularity of the n-th power of a path graph of length at least 3*n.at n=23A363706
