My ASCII skills fail me, but how about one star in the middle, surrounded by similar ellipses of either 6, 8, 10, 12, and 14 stars, where the ellipses are similar ones, and the stars on each underlying ellipse are equispaced w.r.t. arclength. The arrangement of stars has rectangular symmetry, with the "2 mod 4" ellipses of size 6, 10, 14 each having a pair of stars on the y-axis (to emphasize the horizontal elongation), and the "0 mod 4" ellipses of size 8 and 12 stars each having a pair of stars on the x-axis and (hence) a pair on the y-axis. (The same general idea can be tried using ellipses of 9, 10, 11, 12, and 13 stars, but this has less potential symmetry than the above.) --Dan
