Presentation

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

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

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