Si introduce la nozione di M-P-piano e si caratterizzano gli M-P-piani in quanto piani ottenibili da piani affini ordinati desarguesiani mediante una costruzione di “tipo Moulton”. The notion of M-P-planes is investigated. The main result: they are charcterized by the fact that they can be obtained from ordered affine desarguesian planes by means of a suitable construction of “Moulton type”.
