Presentation

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

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

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