Presentation

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

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

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

Polycyclic presentation:
