Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

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

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

Polycyclic presentation:
