Presentation

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

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

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