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

Polycyclic presentation:
