Finite projective planes of order n with a 2-transitive orbit of length n – 3

We characterize the finite projective planes П of order n with a collineation group G acting 2-transitively on a point orbit of length n – 3...

Two-transitive ovals

An oval 𝒪 of a projective plane is called two-transitive if there is a collineation group G fixing 𝒪 and acting 2-transitively on its points...

Automorphisms of Hilbert's non-desarguesian affine plane and its projective closure

Hilbert constructed an early example of a non-desarguesian plane by modifying the lines of the real plane inside an ellipse...
