Presentation

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

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

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

Polycyclic presentation:
