Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 64

A minimal faithful permutation representation — 4 generators on 20 points:

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