Presentation

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

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

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