Presentation

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

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

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