Presentation

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

A minimal faithful permutation representation — 4 generators on 38 points:

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