Presentation

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

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

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