Presentation

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

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

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