Presentation

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

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

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