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