Presentation

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

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

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