Presentation

minimal degree	μ(G) = 32
transitive degree	μ_t(G) = 256

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

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