Presentation

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

A minimal faithful permutation representation — 4 generators on 26 points:

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