Presentation

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

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

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