Presentation

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

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

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