Presentation

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

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

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