Presentation

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

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

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