Presentation

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

A minimal faithful permutation representation — 5 generators on 26 points:

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