Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 6 generators on 20 points:

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