Presentation

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

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

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

Polycyclic presentation:
