Presentation

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

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

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