Presentation

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

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

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