Presentation

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

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

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