Weakly totally permutable products and Fitting classes [PDF]
International Journal of Group Theory, 2021 It is known that if $ G=AB $ is a product of its totally permutable subgroups $ A $ and $ B $, then $ G\in \mathfrak{F} $ if and only if $ A\in \mathfrak{F} $ and $ B\in \mathfrak{F} $ when $ \mathfrak{F} $ is a Fischer class containing the class ...
