• Numbers k such that the period of the continued fraction for sqrt(k) contains exactly 43 ones.at n=20A031811
• 2-dimensional array T(n, k) listed by antidiagonals for n >= 2, k >= 1 giving the number of acyclic paths of length k in the graph G(n) whose vertices are the integer lattice points (p, q) with 0 <= p, q < n and with an edge between v and w iff the line segment [v, w] contains no other integer lattice points.at n=34A247944
• Number of edges in a graph of n adjacent rectangles in a row with all possible diagonals drawn, as in A306302, but without the rectangles' edges which are perpendicular to the row.at n=23A369177
• a(n) is the least integer m such that the sum of the digits of m^2 is k+n where k is the number of digits of n.at n=46A369956
