Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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