Presentation

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

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

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

Polycyclic presentation:
