Presentation

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

A minimal faithful permutation representation — 3 generators on 20 points:

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