Presentation

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

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

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

Polycyclic presentation:
