Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

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

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

Polycyclic presentation:
