Presentation

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

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

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