Presentation

minimal degree	μ(G) = 36
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 4 generators on 36 points:

(2,3)(7,16)(9,20)(13,30)(17,33)(19,25)(21,36)(23,26)(31,35);(1,2,4,3)(5,6,11,14,8,15,10,24)(7,17,25,35,16,33,19,31)(9,21,26,30,20,36,23,13)(12,27,28,18,29,22,32,34);(5,7,8,16)(6,12,15,29)(9,22,20,27)(10,25,11,19)(13,31,30,35)(14,32,24,28)(17,21,33,36)(18,23,34,26);(1,3,4,2)
