Presentation

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

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

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