Presentation

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

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

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