Subgroups

4 conjugacy classes of subgroups.

minimal degree	μ(G) = 30
transitive degree	μ_t(G) = 221

A minimal faithful permutation representation — 1 generator on 30 points:

(1,2,3,4,5,6,7,8,9,10,11,12,13)(14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30)

Construct this group in GAP via the SmallGroups library:

gap> SmallGroup(221, 1);
