Presentation

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

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

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