A conjecture widely attributed to Neumann is that all finite non-desarguesian projective planes contain a Fano subplane. In this note, we show that any finite projective plane of even order which admits an orthogonal polarity contains many Fano subplanes. The number of planes of order less than n previously known to contain a Fano subplane was O (log n), whereas the number of planes of order less than n that our theorem applies to is not bounded above by any polynomial in n.
