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

Polycyclic presentation:
