Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

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

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

Polycyclic presentation:
