Presentation

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

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

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