minimal degreeμ(G) = 37
transitive degreeμt(G) = 160

A minimal faithful permutation representation — 4 generators on 37 points:

(1,2,3,4,5)(6,7)(8,18,22,13)(9,15,10,24)(11,17)(12,16)(14,23,32,25)(19,35)(20,29)(21,34,26,30)(27,33)(28,36)(31,37);(6,8)(7,13)(9,19)(10,20)(11,26)(12,22)(14,31)(15,29)(16,18)(17,34)(21,27)(23,37)(24,35)(25,36)(28,32)(30,33);(6,9,12,10)(7,14,16,32)(8,19,22,20)(11,25,27,23)(13,28,18,31)(15,17,24,33)(21,37,26,36)(29,30,35,34);(6,10,12,9)(7,15,16,24)(8,20,22,19)(11,25,27,23)(13,29,18,35)(14,17,32,33)(21,37,26,36)(28,30,31,34)
