Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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