Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:
