Presentation

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

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

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