Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 128

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

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