Presentation

minimal degreeμ(G) = 32
transitive degreeμt(G) = 256

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

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