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