Presentation

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

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

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