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