• Integer sequence induced by second order Bulgarian solitaire operation on partition list A241918: a(n) = A241909(A243072(A241909(n))).at n=43A243052
• Numbers k = p1^e1*p2^e2, with e1 != e2, such that the Euclidean distance between points (p1, e1) and (p2, e2) is an integer.at n=20A387172
• Square array A(n,k), read by descending antidiagonals, where A(1, k) = A388984(k), and for n > 1, A(n, k) = A003961(A(n-1), k).at n=60A388981
