The Moulton plane is a mathematical structure used in projective geometry. It is named after the mathematician F. W. Moulton, who introduced it in 1910. The Moulton plane is essentially an example of a projective plane which has some interesting properties, particularly involving points and lines. In a standard projective plane, any two lines intersect at exactly one point, and any two points lie on exactly one line. The Moulton plane modifies these properties slightly.
