Presentation

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

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

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