1) Fitting class
Fitting类
1.
Some properties about the class of π-close-Sylow-tower groups are obtained as follows by deducing the characters of π-close-Sylow-tower groups: Class of π-closed-Sylow-tower groups is S-closed, Sn-closed, H-closed, D-closed, R0-closed and N0-closed, so the class of π-closed-Sylow-tower groups is a saturated formation and a Fitting class.
并由此推出 ,π-闭 -Sylow塔群类是一个饱和群系且为一个 Fitting
