Presentation

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

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

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