Presentation

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

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

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

Polycyclic presentation:
