Presentation

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

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

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