Presentation

minimal degree	μ(G) = 20
transitive degree	μ_t(G) = 256

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

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