Presentation

minimal degree	μ(G) = 23
transitive degree	μ_t(G) = 112

A minimal faithful permutation representation — 3 generators on 23 points:

(1,2,7)(3,4,6)(10,17)(11,20)(13,21)(14,19)(16,22)(18,23);(2,3)(4,6)(5,7)(8,10,11,17,12,18,20,23)(9,13,14,22,15,16,19,21);(8,9)(10,16)(11,19)(12,15)(13,18)(14,20)(17,22)(21,23)
