Presentation

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

A minimal faithful permutation representation — 5 generators on 20 points:

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