Presentation

minimal degree	μ(G) = 24
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 24 points:

(5,6,7,8)(9,10,15,20,13,18,14,19)(11,16,22,24,12,23,21,17);(1,2)(3,4)(9,11,14,21)(10,16,19,24)(12,15,22,13)(17,18,23,20);(2,4)(9,12,13,11)(10,17,18,24)(14,22)(15,21)(16,19)(20,23)
