Presentation

minimal degreeμ(G) = 26
transitive degreeμt(G) = 256

A minimal faithful permutation representation — 6 generators on 26 points:

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