Presentation

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

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

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