Presentation

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

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

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