Presentation

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

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

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

Polycyclic presentation:
