Summary

Item	Value
Degrees of irreducible representations over a splitting field (such as ${\overline {\mathbb {Q} }}$ or $\mathbb {C}$)	1,1,1,1,2,8 maximum: 8, lcm: 8, number: 6, sum of squares: 72
Ring generated by character values	$\mathbb {Z}$ -- ring of integers
Field generated by character values	$\mathbb {Q}$ -- field of rational numbers. So the group is a rational group.
