Poncelet's Theorem in the four nonisomorphic finite projective planes of order 9
Katharina Kusejko, Norbert Hungerbühler
We study Poncelet's Theorem in the four non-isomorphic finite projective planes of order 9. Among these planes, only the Desarguesian plane turns out to be a Poncelet plane, while…
