The cosine of the angle between <Burgers vector> and line direction is $1/3$, so the angle is $70.53^\circ$: \b[the <dislocation> is mixed]. Both vectors must lie in its <dislocation glide> plane. Their <cross product> is proportional to
$$
(1,-1,1)\times(1,1,1)=(-2,0,2),
$$
so the plane is \b[$(10\bar1)$], a member of $\{110\}$. The screw component magnitude is $a/(2\sqrt3)$ and the edge component magnitude is $a\sqrt{2/3}$.
