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