Presentation

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

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

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