Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 128

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

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