On projective planes of order less than 32
نویسنده
چکیده
By our count, 245 projective planes of order less than 32 are currently known. This list is dominated by the 193 known planes of order 25. Most of these are either translation planes or Hughes planes, or planes obtained from these by the well-known process of repeatedly dualizing and deriving. We describe two new planes obtainable by the quite different method of ‘lifting quotients’. 2000 Mathematics Subject Classification: 51E15

Reconstructing Projective Planes from Semibiplanes
From a projective plane Π with a homology τ of order 2, one obtains an incidence system having as points and blocks the 〈τ〉-orbits of length 2 on the points and lines of Π, and with incidence inherited from Π. The resulting structure, denoted by Π/τ , is an example of a homology semibiplane. We have shown that a Desarguesian projective plane of odd prime order is uniquely reconstructible from i...
متن کاملSome new results on small blocking semiovals
A blocking semioval S in a projective plane of order q is a set of points such that every line meets S in at least one point (the blocking property), and every point of S lies on a unique tangent line (the semioval property). The set of points on the sides of a triangle, excluding the vertices, is a blocking semioval in any projective plane of order q > 2, and has size 3q − 3. The size of a blo...
متن کاملMutually Unbiased Bases and Finite Projective Planes
It is conjectured that the question of the existence of a set of d + 1 mutually unbiased bases in a ddimensional Hilbert space if d differs from a power of prime is intimatelly linked with the problem whether there exist projective planes whose order d is not a power of prime. Recently, there has been a considerable resurgence of interest in the concept of the so-called mutually unbiased bases ...
متن کاملOn the convex hull of projective planes
We study the finite projective planes with linear programming models. We give a complete description of the convex hull of the finite projective planes of order 2. We give some integer linear programming models whose solution are, either a finite projective (or affine) plane of order n, or a (n + 2)-arc.
متن کاملCyclic Quotients of Fake Projective Planes
Recently, Prasad and Yeung classified all possible fundamental groups of fake projective planes. According to their result, many fake projective planes admit an automorphism of prime order, and in that case the order must be 3 or 7. Let σ be an automorphism of prime order of a fake projective plane X. In this paper we classify all possible structures of the quotient surface X/σ and its minimal ...
