Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 6 generators on 26 points:

(7,8)(9,10)(11,12,14,15)(13,16,18,17)(20,23)(24,25);(12,15)(16,17)(19,20)(21,24)(22,23)(25,26);(4,6)(8,10)(11,12)(13,17)(14,15)(16,18)(19,20)(21,25)(22,23)(24,26);(1,2);(3,4)(5,6)(7,8)(9,10);(11,13)(12,16)(14,18)(15,17)(19,21)(20,24)(22,26)(23,25)
