Presentation

minimal degreeμ(G) = 38
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 38 points:

(7,8,11,17,28,36,12,30,14,19,10,26,13,18,29,16)(9,20,23,15,31,34,24,37,22,32,21,33,25,38,27,35);(3,4,5,6)(7,9)(8,15)(10,24)(11,27)(12,21)(13,31)(14,22)(16,34)(17,20)(18,37)(19,33)(23,29)(25,28)(26,32)(30,38)(35,36);(7,10,13,12,14,11,28,29)(8,16,36,17,19,30,18,26)(9,21,25,24,22,23,31,27)(15,32,37,38,33,20,35,34);(1,2);(9,22)(15,33)(20,32)(21,23)(24,27)(25,31)(34,38)(35,37)
