N-group (finite group theory)
FINITE GROUP ALL OF WHOSE LOCAL SUBGROUPS ARE SOLVABLE
Simple N-group; N-group theorem; N-groups; Minimal simple group
In mathematical finite group theory, an N-group is a group all of whose local subgroups (that is, the normalizers of nontrivial p-subgroups) are solvable groups. The non-solvable ones were classified by Thompson during his work on finding all the minimal finite simple groups.
