Presentation

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

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

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