Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 64

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

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