Presentation

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

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

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