A list of all known projective planes of small order, providing for each plane a text file of point-line incidences and a file of generators of its automorphism group, together with invariants (elementary divisors, automorphism group order, point/line orbit lengths). The main table covers 257 planes of orders 2 through 32, with a companion subpage on the 300,000+ known planes of order 49; completeness of the list is known only for orders up to 10.
