Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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