Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 64

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

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