Abstract

The partitions into Baer subplanes of the Desarguesian projective planes of order \(9\), \(16\), and \(25\) are classified by computer. It is also shown that the non-Desarguesian projective planes of order \(9\) and the non-Desarguesian translation planes of order \(16\) and \(25\) do not admit such a partition.
