Presentation

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

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

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