Presentation

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

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

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