Presentation

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

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

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