Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

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

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