Presentation

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

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

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