%N Squares visited by a (2,5)-leaper on a spirally numbered board and moving to the lowest available unvisited square at each step.
%C Board is numbered with the square spiral:
%C 17--16--15--14--13
%C | |
%C 18 5---4---3 12 .
%C | | | |
%C 19 6 1---2 11 .
%C | | |
%C 20 7---8---9--10 .
%C |
%C 21--22--23--24--25--26
%C The sequence is finite: at step 7574, square 6760 is visited, after which there are no unvisited squares within one move.
