Presentation

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

A minimal faithful permutation representation — 3 generators on 36 points:

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