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