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

Polycyclic presentation:
