Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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