Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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