I have been trying to review my undergraduate work with modern geometries (it's
been too long), and I'm stuck trying to model an affine plane of order 3. The
axioms are taken from "A Course in Modern Geometries", Judith Cederberg,
Springer-Verlag Publishers, 1989 and are as follows:
Axiom 1: There exist at least four points no three of which are collinear.
Axiom 2: There exists at least one line with exactly n (n>1) points on it.
Axiom 3: Given two distinct points, there is exactly one line incident with
both of them.
Axiom 4: Given a line "l" and a point "P" not on line "l", there is exactly
one line through "P" that does not intersect "l"
Somehow I am supposed to model this, then prove that in a plane of order n,
each point lies on exactly n+1 lines. I would welcome any advice and also any
suggestions for further reading to help enhacnce my rather limited
understanding of affine and projective planes.
