Presentation

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

A minimal faithful permutation representation — 4 generators on 20 points:

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

Polycyclic presentation:
