Presentation

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

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

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