Presentation

minimal degree	μ(G) = 40
transitive degree	μ_t(G) = 256

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

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