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