Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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