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