Presentation

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

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

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