Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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