Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 40 points:

(1,2,5,8)(3,4,7,6)(9,10,11,16,13,18,14,15)(12,20,21,24,22,23,19,17);(1,3,5,7)(2,6,8,4)(9,11,13,14)(10,15,18,16)(12,21,22,19)(17,23,24,20)(25,26)(27,34)(28,32)(29,37)(30,33)(31,35)(36,39)(38,40);(1,4,5,6)(2,7,8,3)(10,16)(11,14)(15,18)(17,23)(19,21)(20,24)(25,27,30,36)(26,31,33,40)(28,35,29,38)(32,39,37,34);(2,8)(3,7)(9,12,13,22)(10,17,18,24)(11,19,14,21)(15,20,16,23)(25,28,30,29)(26,32,33,37)(27,35,36,38)(31,39,40,34)
