Presentation

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

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

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