How many eclipsed and staggered conformations of ethane are obtained during a $0^{\circ}$ to $360^{\circ}$ rotation about the $C-C$ bond?

(3 ECLIPSED AND 3 STAGGERED) During a full $360^{\circ}$ rotation about the $C-C$ bond in ethane,the molecule passes through various conformational states.
$1$. Eclipsed conformations: These occur at $0^{\circ}$,$120^{\circ}$,and $240^{\circ}$. Thus,there are $3$ eclipsed conformations.
$2$. Staggered conformations: These occur at $60^{\circ}$,$180^{\circ}$,and $300^{\circ}$. Thus,there are $3$ staggered conformations.
Therefore,a total of $3$ eclipsed and $3$ staggered conformations are obtained.
