Presentation

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

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

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

Polycyclic presentation:
