Presentation

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

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

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

Polycyclic presentation:
