Presentation

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

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

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

Polycyclic presentation:
