Presentation

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

A minimal faithful permutation representation — 6 generators on 20 points:

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

Polycyclic presentation:
