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