Subgroups

4 conjugacy classes of subgroups.

minimal degree	μ(G) = 44
transitive degree	μ_t(G) = 123

A minimal faithful permutation representation — 1 generator on 44 points:

(1,2,3)(4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44)

Construct this group in GAP via the SmallGroups library:

gap> SmallGroup(123, 1);
