Hall operators on the set of formations of finite groups

Let \(\pi\) be a nonempty set of primes and let  \(\frak{F}\)  be a saturated formation of all finite soluble \(\pi\)-groups. It is constructed the saturated formation consisting of all finite \(\pi\)-soluble groups whose \(\frak{F}\)-projectors contain a Hall \(\pi\)-subgroup.
