Характеризация черниковских групп в классе групп Шункова с четверной силовской $2$-подгруппой

We consider groups whose Sylow $2$-subgroup is a four-group $L$ and the centralizers of involutions of $L$ are Chernikov groups. Under these circumstances we have obtained a characterization of Chernikov groups in a class of Shunkov groups.
