Presentation

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

A minimal faithful permutation representation — 3 generators on 32 points:

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