Presentation

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

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

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