Presentation

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

A minimal faithful permutation representation — 7 generators on 26 points:

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