Presentation

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

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

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

Polycyclic presentation:
