Presentation

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

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

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