BiographyEdit

Frattini entered the University of Rome in 1869, where he studied mathematics with Giuseppe Battaglini, Eugenio Beltrami, and Luigi Cremona, obtaining his Laurea in 1875.

In 1885 he published a paper where he defined a certain subgroup of a finite group. This subgroup, now known as the Frattini subgroup, is the subgroup   generated by all the non-generators of the group  . He showed that   is nilpotent and, in so doing, developed a method of proof known today as Frattini's argument.[1]
