Presentation

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

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

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

Polycyclic presentation:
