Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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