Presentation

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

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

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

Polycyclic presentation:
