Presentation

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

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

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

Polycyclic presentation:
