Presentation

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

A minimal faithful permutation representation — 5 generators on 20 points:

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

Polycyclic presentation:
