Gino Fano was an Italian mathematician born in 1871 who made important contributions to geometry and group theory. He studied under Felix Klein and published works on continuous groups, geometric classification, and the foundations of geometry. Fano is particularly known for introducing the Fano plane in 1892, a famous model of projective geometry consisting of 7 points and 7 lines with specific incidence properties. Finite projective planes can be characterized by an order parameter, with the Fano plane having order 2. The Fano plane has been used as a model in applications such as switching networks, games like Fire and Ice, and the game of Nim.
