Presentation

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

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

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

Polycyclic presentation:
