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