Presentation

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

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

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