Presentation

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

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

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