Presentation

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

A minimal faithful permutation representation — 5 generators on 26 points:

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