Presentation

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

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

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