Presentation

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

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

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