Presentation

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

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

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