Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 32

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

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

Polycyclic presentation:
