Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 512

A minimal faithful permutation representation — 4 generators on 32 points:

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