Presentation

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

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

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

Polycyclic presentation:
