Presentation

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

A minimal faithful permutation representation — 5 generators on 26 points:

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