Presentation

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

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

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