Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 512

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

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