Presentation

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

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

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