Presentation

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

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

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