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

Polycyclic presentation:
