• Triangular array read by rows: a(n, k) = number of ordered factorizations of a "hook-type" number with n total prime factors and k distinct prime factors. "Hook-type" means that only one prime can have multiplicity > 1.at n=33A098348
• Smallest k > 1 such that (sum of digits of k^n)*(sum of digits of k^(n+1)) = k, or 0 if no such k exists.at n=16A126783
• A tabular sequence of arrays counting ordered factorizations over least prime signatures. The unordered version is described by sequence A129306.at n=49A131420
• Numbers n such that n^3 can be represented as sum of (at least two) consecutive squares.at n=15A163390
• a(n) is the number of ordered partitions of {1, 1, 1, 2, 3, ..., n-2}.at n=7A172110
• Integers m such that m^3 is the sum of two or more consecutive integer squares.at n=29A212018
• Number of (n+1) X (2+1) 0..2 arrays with the upper median of every 2 X 2 subblock differing from its horizontal and vertical neighbors by exactly one.at n=9A237631
