Presentation

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

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

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