Presentation

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

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

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