Presentation

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

A minimal faithful permutation representation — 3 generators on 20 points:

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

Polycyclic presentation:
