Presentation

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

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

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