Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:
