Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 32 points:

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