Presentation

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

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

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