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

Polycyclic presentation:
