Presentation

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

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

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

Polycyclic presentation:
