Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

A minimal faithful permutation representation — 5 generators on 20 points:

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