Presentation

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

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

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